Describe the feature:

Elasticsearch version :6.2.4

Plugins installed: ingest-geoip, ingest-user-agent

JVM version :

openjdk version "1.8.0_161"
OpenJDK Runtime Environment (build 1.8.0_161-b14)
OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)

OS version :

Linux elasticsearch-0 4.18.0-21-generic #22~18.04.1-Ubuntu SMP Thu May 16 15:07:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Description of the problem including expected versus actual behavior:
Problem: elasticsearch-0 kept crashing due to Failed to read local state, exiting....
Expected: elasticsearch could bootup successfully.
Description: We are running a one ES instance in k8s pod. It kept reporting below error(Please refer to more detailed error and config at the end of this issue). According to the link, metadata seems corrupted. We removed the corrputed data and ES could bootup. Can someone help to give the hit why this happened? What should be done to avoid this issue. Thanks in advance.

failed to read [id:121, legacy:false, file:/usr/share/elasticsearch/data/nodes/0/indices/lN_rrlwwSTmqxGn2Vi_2Tg/_state/state-121.st]

Steps to reproduce:

  1. Leave old ES data
  2. Delete crashed ES pod
  3. Restart ES pod

Looks the ES 6.2.4 es node is reading a data directory that was used by an es node with a higher version. Looking at the stack trace, the mapping_version field was introduced in #33147, which was included in the 6.5 release. Did you do an upgrade to a newer version and then downgraded to 6.2.4 using the same data directory?

@martijnvg Thanks for your help. Yes, we tested different versions on same virtual machine without cleaning old ES data. The main versions being used are 6.7.2 and 6.2.4.

So when we test 6.2.4 version, we need to remove data generated by ES that has version higher than 6.5 release? This is the only way to let version 6.2.4 ES work as expected, right?

Elasticsearch supports upgrading to a newer version with the same data directory. However Elasticsearch doesn't support downgrading to an older version with the same data directory. In that case the data directory should be removed. In any case when upgrading please consult the upgrade docs: https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-upgrade.html

I'm going to close this issue. Actually we use GitHub for verified bug reports, feature requests, and pull requests. Next time we would really appreciate if you go to the forums first before opening an issue here. If you do have a followup question then open a thread in the Elasticsearch forum and then I'm happy to help you there.

Happened to me on a test instance, which I tested a newer ES version on and then forgot, upon rerunning our infra provisioning the version was downgraded to 6.8 again.

For me the simple fix was just to remove all states like this:

rm -r /data/elasticsearch/nodes/0/indices/*/_state/
rm -r /data/elasticsearch/nodes/0/_state/

(where /data/elasticsearch is my data dir)

So I could at least run elasticsearch again. This however might lead to data loss! So no guarantees here.

I tried to downgrade Es from 7 > 6.8.22. I got the same exceptions like org.elasticsearch.ElasticsearchException: java.io.IOException: failed to read [id:19, file:/var/lib/elasticsearch/nodes/0/_state/node-19.st] etc.... I removed $rm -rf /var/lib/elasticsearch (this folder remained in the system after the removal of es 7. Then reinstalled Es 6.8 and its worked. thanks to @martijnvg @showalski
