In the Sys V init scripts, we check for Java. This is not needed, since the same check happens in elasticsearch-env when starting up. Having this duplicate check has bitten us in the past, where we made a change to the logic in elasticsearch-env, but missed updating it here. Since there is no need for this duplicate check, we remove it from the Sys V init scripts.

* Fsync translog without writeLock before rolling (#45765)
Today, when rolling a new translog generation, we block all write
threads until a new generation is created. This choice is perfectly
fine except in a highly concurrent environment with the translog
async setting. We can reduce the blocking time by pre-sync the
current generation without writeLock before rolling. The new step
would fsync most of the data of the current generation without
blocking write threads.

* Update joda to 2.10.3 (#45495)
* Allow partial request body reads in AWS S3 retries tests (#45847)
This commit changes the tests added in #45383 so that the fixture that
emulates the S3 service now sometimes consumes all the request body
before sending an error, sometimes consumes only a part of the request
body and sometimes consumes nothing. The idea here is to beef up a bit
the tests that writes blob because the client's retry logic relies on
marking and resetting the blob's input stream.
This pull request also changes the testWriteBlobWithRetries() so that it
(rarely) tests with a large blob (up to 1mb), which is more than the client's
default read limit on input streams (131Kb).
Finally, it optimizes the ZeroInputStream so that it is a bit more effective
(now works using an internal buffer and System.arraycopy() primitives).

* [ML] Improve progress reportings for DF analytics (#45856)
Previously, the stats API reports a progress percentage
for DF analytics tasks that are running and are in the
`reindexing` or `analyzing` state.
This means that when the task is `stopped` there is no progress
reported. Thus, one cannot distinguish between a task that never
run to one that completed.
In addition, there are blind spots in the progress reporting.
In particular, we do not account for when data is loaded into the
process. We also do not account for when results are written.
This commit addresses the above issues. It changes progress
to being a list of objects, each one describing the phase
and its progress as a percentage. We currently have 4 phases:
reindexing, loading_data, analyzing, writing_results.
When the task stops, progress is persisted as a document in the
state index. The stats API now reports progress from in-memory
if the task is running, or returns the persisted document
(if there is one).
* Expose the ability to cancel async requests in REST high-level client (#45688)
This commits makes all the async methods in the high level client return the `Cancellable` object that the low level client now exposes.
Relates to #45379
Closes #44802
* Fix IngestService to respect original document content type (#45799)
This PR modifies the logic in IngestService to preserve the original content type
on the IndexRequest, such that when a document with a content type like SMILE
is submitted to a pipeline, the resulting document that is persisted will remain in
the original content type (SMILE in this case).
* Change `{var}` convention to `<var>` (#45904)
* Fix bugs in Painless SCatch node (#45880)
This fixes two bugs:
- A recently introduced bug where an NPE will be thrown if a catch block is
empty.
- A long-time bug where an NPE will be thrown if multiple catch blocks in a
row are empty for the same try block.
* Update translog checkpoint after marking ops as persisted (#45634)
If two translog syncs happen concurrently, then one can return before
its operations are marked as persisted. In general, this should not be
an issue; however, peer recoveries currently rely on this assumption.

* Remove non task aware execute methods from TransportAction (#45821)
The TransportAction class has several ways to execute the action, some
of which will create a task. This commit removes those non task aware
variants in favor of handling task creation inside NodeClient for local
actions.
* Remove the pidfile setting (#45940)
The pidfile setting was deprecated in version 7.4.0 of Elasticsearch for
removal in Elasticsearch 8.0.0. This commit removes the pidfile setting.
* Allow Transport Actions to indicate authN realm (#45767)
This commit allows the Transport Actions for the SSO realms to
indicate the realm that should be used to authenticate the
constructed AuthenticationToken. This is useful in the case that
many authentication realms of the same type have been configured
and where the caller of the API(Kibana or a custom web app) already
know which realm should be used so there is no need to iterate all
the realms of the same type.
The realm parameter is added in the relevant REST APIs as optional
so as not to introduce any breaking change.

Today if non-TLS record is received on TLS port generic exception will

* Fix Broken HTTP Request Breaking Channel Closing (#45958)
This is essentially the same issue fixed in #43362 but for http request
version instead of the request method. We have to deal with the
case of not being able to parse the request version, otherwise
channel closing fails.
Fixes #43850
* Refactor RepositoryCredentialsTests (#45919)
This commit refactors the S3 credentials tests in
RepositoryCredentialsTests so that it now uses a single
node (ESSingleNodeTestCase) to test how secure/insecure
credentials are overriding each other. Using a single node
makes it much easier to understand what each test is actually
testing and IMO better reflect how things are initialized.
It also allows to fold into this class the test
testInsecureRepositoryCredentials which was wrongly located
in S3BlobStoreRepositoryTests. By moving this test away, the
S3BlobStoreRepositoryTests class does not need the
allow_insecure_settings option anymore and thus can be
executed as part of the usual gradle test task.
* [DOCS] Reformat get settings API docs (#45924)
* Better logging for TLS message on non-secure transport channel (#45835)
This commit enhances logging for 2 cases:
1. If non-TLS enabled node receives transport message from TLS enabled
node on transport port.
2. If non-TLS enabled node receives HTTPs request on transport port.
* Relax translog assertion in testRestoreLocalHistoryFromTranslog (#45943)
Since #45473, we trim translog below the local checkpoint of the safe
commit immediately if soft-deletes enabled. In
testRestoreLocalHistoryFromTranslog, we should have a safe commit after
recoverFromTranslog is called; then we will trim translog files which
contain only operations that are at most the global checkpoint.
With this change, we relax the assertion to ensure that we don't put
operations to translog while recovering history from the local translog.
* Consider artifact repositories backed by S3 secure (#45950)
Since credentials are required to access such a repository, and these
repositories are accessed over an encrypted protocol (https), this
commit adds support to consider S3-backed artifact repositories as
secure. Additionally, we add tests for this functionality.
* Build: Support `console-result` language (#45937)
This adds support for verifying that snippets with the `console-result`
language are valid json. It also switches the response snippets on the
`docs/get` page from `js` to `console-result` which will allow clients
to provide "alternatives" for them like they can now do with
`// CONSOLE` snippets.
* [DOCS] Reformat indices exists API docs (#45918)
* [DOCS] Reformat get field mapping API docs (#45700)
* Add Cumulative Cardinality agg (and Data Science plugin) (#43661)
This adds a pipeline aggregation that calculates the cumulative
cardinality of a field. It does this by iteratively merging in the
HLL sketch from consecutive buckets and emitting the cardinality up
to that point.
This is useful for things like finding the total "new" users that have
visited a website (as opposed to "repeat" visitors).
This is a Basic+ aggregation and adds a new Data Science plugin
to house it and future advanced analytics/data science aggregations.
* [DOCS] Correct `IIF` conditional section title (#45979)
* Fix typo in plugin name, add to allowed settings
* PKI realm authentication delegation (#45906)
This commit introduces PKI realm delegation. This feature
supports the PKI authentication feature in Kibana.
In essence, this creates a new API endpoint which Kibana must
call to authenticate clients that use certificates in their TLS
connection to Kibana. The API call passes to Elasticsearch the client's
certificate chain. The response contains an access token to be further
used to authenticate as the client. The client's certificates are validated
by the PKI realms that have been explicitly configured to permit
certificates from the proxy (Kibana). The user calling the delegation
API must have the delegate_pki privilege.
Closes #34396
* [ML] fixing bug where analytics process starts with 0 rows (#45879)
The native process requires that there be a non-zero number of rows to analyze. If the flag --rows 0 is passed to the executable, it throws and does not start.
When building the configuration for the process we should not start the native process if there are no rows.
Adding some logging to indicate what is occurring.

* [TEST] wait for search task to be cancelled in SearchRestCancellationIT (#45978)
SearchRestCancellationIT aborts an http request, and then checks that
the corresponding search task has been cancelled on the server-side.
There are no guarantees that the task has already been marked cancelled
after the `cancel` calls returns, and there is no easy wait for that.
This commit introduces an assertBusy to try and wait for the search task
to be marked cancelled.
Closes #45911
* Remove node settings from blob store repositories (#45991)
This commit starts from the simple premise that the use of node settings
in blob store repositories is a mistake. Here we see that the node
settings are used to get default settings for store and restore throttle
rates. Yet, since there are not any node settings registered to this
effect, there can never be a default setting to fall back to there, and
so we always end up falling back to the default rate. Since this was the
only use of node settings in blob store repository, we move them. From
this, several places fall out where we were chaining settings through
only to get them to the blob store repository, so we clean these up as
well. That leaves us with the changeset in this commit.

Currently we use a custom CopyBytesSocketChannel for interfacing with

writes. This commit adds a test for this behavior.
* Do not create engine under IndexShard#mutex (#45263)
Today we create new engines under IndexShard#mutex. This is not ideal
because it can block the cluster state updates which also execute under
the same mutex. We can avoid this problem by creating new engines under
a separate mutex.

* Don't use assemble task on root project (#45999)
The root project uses the base plugin to get a clean task, but does not
actually need the assemble task. This commit changes the root project to
use the lifecycle-base plugin, which while still creating the assemble
task, won't add any dependencies to it.
* [DOCS] Fix typo. (#46006)
* [TEST] wait for http channels to be closed in ESIntegTestCase (#45977)
We recently added a check to `ESIntegTestCase` in order to verify that
no http channels are being tracked when we close clusters and the
REST client. Close listeners though are invoked asynchronously, hence
this check may fail if we assert before the close listener that removes
the channel from the map is invoked.
With this commit we add an `assertBusy` so we try and wait for the map
to be empty.
Closes #45914
Closes #45955
* Add `manage_own_api_key` cluster privilege (#45897)
The existing privilege model for API keys with privileges like
`manage_api_key`, `manage_security` etc. are too permissive and
we would want finer-grained control over the cluster privileges
for API keys. Previously APIs created would also need these
privileges to get its own information.
This commit adds support for `manage_own_api_key` cluster privilege
which only allows api key cluster actions on API keys owned by the
currently authenticated user. Also adds support for retrieval of
the API key self-information when authenticating via API key
without the need for the additional API key privileges.
To support this privilege, we are introducing additional
authentication context along with the request context such that
it can be used to authorize cluster actions based on the current
user authentication.
The API key get and invalidate APIs introduce an `owner` flag
that can be set to true if the API key request (Get or Invalidate)
is for the API keys owned by the currently authenticated user only.
In that case, `realm` and `username` cannot be set as they are
assumed to be the currently authenticated ones.
The changes cover HLRC changes, documentation for the API changes.
Closes #40031
* Partly revert globalInfo.ready check (#45960)
This check was introduced in #41392 but had the unwanted side-effect
that the keystore settings in such blocks would note be added in the
node's keystore. Given that we have a mid-term plan for FIPS testing
that would made such checks unnecessary, and that the conditional
in these two cases is not really that important, this change removes
this conditional logic so that full-cluster-restart and rolling
upgrade tests will run with PEM files for key/certificate material
no matter if we're in a FIPS JVM or not.
Resolves: #45475
* [ML] Add option to regression to randomize training set (#45969)
Adds a parameter `training_percent` to regression. The default
value is `100`. When the parameter is set to a value less than `100`,
from the rows that can be used for training (ie. those that have a
value for the dependent variable) we randomly choose whether to actually
use for training. This enables splitting the data into a training set and
the rest, usually called testing, validation or holdout set, which allows
for validating the model on data that have not been used for training.
Technically, the analytics process considers as training the data that
have a value for the dependent variable. Thus, when we decide a training
row is not going to be used for training, we simply clear the row's
dependent variable.
* Disallow partial results when shard unavailable (#45739)
Searching with `allowPartialSearchResults=false` could still return
partial search results during recovery. If a shard copy fails
with a "shard not available" exception, the failure would be ignored and
a partial result returned. The one case where this is known to happen
is when a shard copy is recovering when searching, since
`IllegalIndexShardStateException` is considered a "shard not available"
exception.

* Fix RegressionTests#fromXContent (#46029)

* Remove already exist assertion while renew ccr lease (#46009)
If a CCR lease is disappeared while we are renewing it, then we will
issue asyncAddRetentionLease to add that lease. And if
asyncAddRetentionLease takes longer than retentionLeaseRenewInterval,
then we can issue another asyncAddRetentionLease request. One of
asyncAddRetentionLease requests will fail with
RetentionLeaseAlreadyExistsException, hence trip the assertion.
Closes #45192
* Watcher max_iterations with foreach action execution (#45715)
Prior to this commit the foreach action execution had a hard coded
limit to 100 iterations. This commit allows the max number of
iterations to be a configuration ('max_iterations') on the foreach
action. The default remains 100.
* [DOCS] Reformat update index settings API docs (#45931)
* Always add Java-9 style file permissions (#46050)
Java 9 removed pathname canonicalization, which means that we need to
add permissions for the path and also the real path when adding file
permissions. Since master requires a minimum runtime of JDK 11, we no
longer need conditional logic here to apply this pathname
canonicalization with our bares hands. This commit removes that
conditional pathname canonicalization.
* [ML][HLRC] Add data frame analytics regression analysis (#46024)

* Fix rollover alias in SLM history index template (#46001)
This commit adds the `rollover_alias` setting required for ILM to work
correctly to the SLM history index template and adds assertions to the
SLM integration tests to ensure that it works correctly.
* Handle no-op document level failures (#46083)
Today we assume that document failures can not occur for no-ops. This
assumption is bogus, as they can fail for a variety of reasons such as
the Lucene index having reached the document limit. Because of this
assumption, we were asserting that such a document-level failure would
never happen. When this bogus assertion is violated, we fail the node, a
catastrophe. Instead, we need to treat this as a fatal engine exception.
* Remove plugins dir reference from docs (#46047)
While the plugin installation directory used to be settable, it has not
been so for several major versions. This commit removes a lingering
reference to the plugins directory in upgrade docs.

* Use float instead of double for query vectors. (#46004)
Currently, when using script_score functions like cosineSimilarity, the query
vector is treated as an array of doubles. Since the stored document vectors use
floats, it seems like the least surprising behavior for the query vectors to
also be float arrays.
In addition to improving consistency, this change may help with some
optimizations we have been considering around vector dot product.
* Add Circle Processor (#43851)
add circle-processor that translates circles to polygons
* [ML] Throw an error when a datafeed needs CCS but it is not enabled for the node (#46044)
Though we allow CCS within datafeeds, users could prevent nodes from accessing remote clusters. This can cause mysterious errors and difficult to troubleshoot.
This commit adds a check to verify that `cluster.remote.connect` is enabled on the current node when a datafeed is configured with a remote index pattern.

We currently configure io.netty.allocator.numDirectArenas to be 0 in the
jvm erconomics class. This is a config that we always want to set, so it
makes sense to move it to jvm.options.
* Handle delete document level failures (#46100)
Today we assume that document failures can not occur for deletes. This
assumption is bogus, as they can fail for a variety of reasons such as
the Lucene index having reached the document limit. Because of this
assumption, we were asserting that such a document-level failure would
never happen. When this bogus assertion is violated, we fail the node, a
catastrophe. Instead, we need to treat this as a fatal engine exception.

* Flush engine after big merge (#46066)
Today we might carry on a big merge uncommitted and therefore
occupy a significant amount of diskspace for quite a long time
if for instance indexing load goes down and we are not quickly
reaching the translog size threshold. This change will cause a
flush if we hit a significant merge (512MB by default) which
frees diskspace sooner.
* Docs _cat/health verification fix (#46064)
The _cat/health call in getting-started assumes that the master task max

* Replace MockAmazonS3 usage in S3BlobStoreRepositoryTests by a HTTP server (#46081)
This commit removes the usage of MockAmazonS3 in S3BlobStoreRepositoryTests
and replaces it by a HttpServer that emulates the S3 service. This allows the
repository tests to use the real Amazon's S3 client under the hood in tests and will
allow to test the behavior of the snapshot/restore feature for S3 repositories by
simulating random server-side internal errors.
The HTTP server used to emulate the S3 service is intentionally simple and minimal
to keep things understandable and maintainable. Testing full client options on the
server side (like authentication, chunked encoding etc) remains the responsibility
of the AmazonS3Fixture.
* Avoid overshooting watermarks during relocation (#46079)
Today the `DiskThresholdDecider` attempts to account for already-relocating
shards when deciding how to allocate or relocate a shard. Its goal is to stop
relocating shards onto a node before that node exceeds the low watermark, and
to stop relocating shards away from a node as soon as the node drops below the
high watermark.
The decider handles multiple data paths by only accounting for relocating
shards that affect the appropriate data path. However, this mechanism does not
correctly account for _new_ relocating shards, which are unwittingly ignored.
This means that we may evict far too many shards from a node above the high
watermark, and may relocate far too many shards onto a node causing it to blow
right past the low watermark and potentially other watermarks too.
There are in fact two distinct issues that this PR fixes. New incoming shards
have an unknown data path until the `ClusterInfoService` refreshes its
statistics. New outgoing shards have a known data path, but we fail to account
for the change of the corresponding `ShardRouting` from `STARTED` to
`RELOCATING`, meaning that we fail to find the correct data path and treat the
path as unknown here too.
This PR also reworks the `MockDiskUsagesIT` test to avoid using fake data paths
for all shards. With the changes here, the data paths are handled in tests as
they are in production, except that their sizes are fake.

* Ensure top docs optimization is fully disabled for queries with unbounded max scores. (#46105)
When a query contains a mandatory clause that doesn't track the max score per
block, we disable the max score optimization. Previously, we were doing this by
wrapping the collector with a FilterCollector that always returned
ScoreMode.COMPLETE.
However we weren't adjusting totalHitsThreshold, so the collector could still
call Scorer#setMinCompetitiveScore. It is against the method contract to call
setMinCompetitiveScore when the score mode is COMPLETE, and some scorers like
ReqOptSumScorer throw an error in this case.
This commit tries to disable the optimization by always setting
totalHitsThreshold to max int, as opposed to wrapping the collector.

* Remove insecure settings (#46147)
This commit removes the oxymoron of insecure secure settings from the
code base. In particular, we remove the ability to set the access_key

keystore. Thus, it also removes some leniency where these settings could
be placed in the elasticsearch.yml, would not be rejected there, but
would not be consumed for any purpose.
* Inject random errors in S3BlobStoreRepositoryTests (#46125)
This commit modifies the HTTP server used in S3BlobStoreRepositoryTests
so that it randomly returns server errors for any type of request executed by
the SDK client. It is now possible to verify that the repository tests are s
uccessfully completed even if one or more errors were returned by the S3
service in response of a blob upload, a blob deletion or a object listing request
etc.
Because injecting errors forces the SDK client to retry requests, the test limits
the maximum errors to send in response for each request at 3 retries.

* Enhanced logging when transport is misconfigured to talk to HTTP port (#45964)
If a node is misconfigured to talk to remote node HTTP port (instead of
transport port) eventually it will receive an HTTP response from the
remote node on transport port (this happens when a node sends
accidentally line terminating byte in a transport request).
If this happens today it results in a non-friendly log message and a
long stack trace.
This commit adds a check if a malformed response is HTTP response. In
this case, a concise log message would appear.

expectation. The snapshot of this method includes only readers
containing operations in the requesting range.

commit adds variants of test and integTest tasks for netty which set the
unpooled and direct buffer pooled allocators.
relates #45881
* Stabilize SLM REST Tests (#46195)
Unfortunately, #42791 destabilized SLM tests because those tests use
rate limiting the snapshot write rate to a very low value globally.
Now that the various files in a snapshot get uploaded in parallel
this can lead to a few threads in parallel way overshooting the low
value throughput value used by the rate limiter and then making it
wait for minutes which times out the tests that then try to abort
the snapshot (see #21759 for details, aborting a snapshot only
happens when writing bytes to the repository).
For now the old behavior of the test from before my changes can
be restored by moving to a single threaded snapshot pool but
we should find a better way of testing the SLM behaviour here in
a follow-up.

* Cleanup BlobStoreRepository Abort and Failure Handling (#46208)
Aborts and failures were handled in a somewhat unfortunate way in #42791:
Since the tasks for all files are generated before uploading they are all executed when a snapshot is aborted and lead to a massive number of failures added to the original aborted exception.
In the case of failures the situation was not very reasonable as well. If one blob fails uploading the snapshot logic would upload all the remaining files as well and then fail (when previously it would just fail all following files).
I fixed both of the above issues, by just short-circuiting all remaining tasks for a shard in case of an exception in any one upload.
* Test fix for PinnedQueryBuilderIT (#46187)
Fix test issue to stabilise scoring through use of DFS search mode.

* Closes #45956
* Disable request throttling in S3BlobStoreRepositoryTests (#46226)
When some high values are randomly picked up - for example the number
of indices to snapshot or the number of snapshots to create - the tests in S3BlobStoreRepositoryTests can generate a high number of requests to
the internal S3 server.
In order to test the retry logic of the S3 client, the internal server is
designed to randomly generate random server errors. When many
requests are made, it is possible that the S3 client reaches its maximum
number of successive retries capacity. Then the S3 client will stop
retrying requests until enough retry attempts succeed, but it means
that any request could fail before reaching the max retries count and
make the test fail too.

* [ML-DataFrame] Fix off-by-one error in checkpoint operations_behind (#46235)
Fixes a problem where operations_behind would be one less than
expected per shard in a new index matched by the data frame
transform source pattern.
For example, if a data frame transform had a source of foo*
and a new index foo-new was created with 2 shards and 7 documents
indexed in it then operations_behind would be 5 prior to this
change.
The problem was that an empty index has a global checkpoint
number of -1 and the sequence number of the first document that
is indexed into an index is 0, not 1. This doesn't matter for
indices included in both the last and next checkpoints, as the
off-by-one errors cancelled, but for a new index it affected
the observed result.

* Multi-get requests should wait for search active (#46283)
When a shard has fallen search idle, and a non-realtime multi-get
request is executed, today such requests do not wait for the shard to
become search active and therefore such requests do not wait for a
refresh to see the latest changes to the index. This also prevents such
requests from triggering the shard as non-search idle, influencing the
behavior of scheduled refreshes. This commit addresses this by attaching
a listener to the shard search active state for multi-get requests. In
this way, when the next scheduled refresh is executed, the multi-get
request will then proceed.

* Build: Enable testing without magic comments (#46180)
Previously we only turned on tests if we saw either `// CONSOLE` or
`// TEST`. These magic comments are difficult for the docs build to deal
with so it has moved away from using them where possible. We should
catch up. This adds another trigger to enable testing: marking a snippet
with the `console` language. It looks like this:
```
[source,console]
----
GET /
----
```
This saves a line which is nice, I guess. But it is more important to me
that this is consistent with the way the docs build works now.
Similarly this enables response testing when you mark a snippet with the
language `console-result`. That looks like:
```
[source,console-result]
----
{
"result": "0.1"
}
----
```
`// TESTRESPONSE` is still available for situations like `// TEST`: when
the response isn't *in* the console-result language (like `_cat`) or
when you want to perform substitutions on the generated test.

With this commit, Elasticsearch will no longer prefer using shards in the same location

Instead, adaptive replica selection (the default since 7.0) should route requests more efficiently
using the service time of prior inter-node communications. Clusters with big latencies between
nodes should switch to cross cluster replication to isolate nodes within the same zone.
Note that this change only targets 8.0 since it is considered as breaking. However a follow up
pr should add an option to activate this behavior in 7.x in order to allow users to opt-in early.

Unfortunately, with this change, we won't clean up all unreferenced

implementation guarantees this assumption by syncing translog every time
after we remove a translog reader. This change, however, only syncs
translog once after we have removed all unreferenced readers (can be
more than one) and breaks the assumption.

The HTTP server used to emulate the Storage service is intentionally simple
and minimal to keep things understandable and maintainable. Testing full
client options on the server side (like authentication, chunked encoding
etc) remains the responsibility of the GoogleCloudStorageFixture.

* [ML] Extract DataFrameAnalyticsTask into its own class (#46402)
This refactors `DataFrameAnalyticsTask` into its own class.
The task has quite a lot of functionality now and I believe it would
make code more readable to have it live as its own class rather than
an inner class of the start action class.
* Mute CcrRollingUpgradeIT.testUniDirectionalIndexFollowing and testUniDirectionalIndexFollowing (#46429)
Relates #46416
* Mute SSLClientAuthTests.testThatHttpFailsWithoutSslClientAuth()
Tracked in #46230
* Add yet more logging around index creation (#46431)
Further investigation into #46091, expanding on #46363, to add even more
detailed logging around the retry behaviour during index creation.
* [Transform] simplify class structure of indexer (#46306)
simplify transform task and indexer
- remove redundant transform id
- moving client data frame indexer (and builder) into a separate file
* [ML] Tolerate total_search_time_ms not mapped in get datafeed stats (#46432)
ML users who upgrade from versions prior to 7.4 to 7.4 or later
will have ML results indices that do not have mappings for the
total_search_time_ms field. Therefore, when searching these
indices we must tolerate this field not having a mapping.
Fixes #46437
* [DOCS] Adds progress parameter description to the GET stats data frame analytics API doc. (#46434)
* [DOCS] Resort common-parms (#46419)
* [DOCS] Change // CONSOLE comments to [source,console] (#46441)
* [DOCS] Add index alias definition to glossary (#46339)
* [Docs] Fix typo in field-names-field.asciidoc (#46430)
* [DOCS] [5 of 5] Change // TESTRESPONSE comments to [source,console-results] (#46449)
* [DOCS] Correct definition for `allow_no_indices` parameter (#46450)
* Increase REST-Test Client Timeout to 60s (#46455)
We are seeing requests take more than the default 30s
which leads to requests being retried and returning
unexpected failures like e.g. "index already exists"
because the initial requests that timed out, worked
out functionally anyway.
=> double the timeout to reduce the likelihood of
the failures described in #46091
=> As suggested in the issue, we should in a follow-up
turn off retrying all-together probably
* [DOCS] Remove cat request from Index Segments API requests (#46463)
* SQL: fix scripting for grouped by datetime functions (#46421)
* Fix issue with painless scripting not being correctly generated when
datetime functions are used for GROUPing of an INTERVAL operation.
* Use `null` schema response for `SYS TABLES` command. (#46386)
* Ignore replication for noop updates (#46458)
Previously, we ignore replication for noop updates because they do not
have sequence numbers. Since #44603, we started assigning sequence
numbers to noop updates leading them to be replicated to replicas.
This bug occurs only on 8.0 for it requires #41065 and #44603.
Closes #46366
* Strengthen testUpdate in rolling upgrade
We hit a bug where we can't partially update documents created in a
mixed cluster between 5.x and 6.x. Although this bug does not affect
7.0 or later, we should have a good test that catches this issue.

In the Sys V init scripts, we check for Java. This is not needed, since the same check happens in elasticsearch-env when starting up. Having this duplicate check has bitten us in the past, where we made a change to the logic in elasticsearch-env, but missed updating it here. Since there is no need for this duplicate check, we remove it from the Sys V init scripts.
