Moving building to an IndexBuildManager. This helps abstract some of the details of building away from the Indexer. Also, means we can leak less of the details of the implementation away (though not as many as I'd like) Adding some more logging and interruptibility to acquiring the INDEX_UPDATE lock to help minimize locking risks for server shutdown. --- .../hbase/index/IndexBuildManager.java | 260 ++++++++++++++++++ .../hbase/index/IndexLogRollSynchronizer.java | 1 + .../com/salesforce/hbase/index/Indexer.java | 96 ++++--- .../hbase/index/builder/BaseIndexBuilder.java | 16 ++ .../hbase/index/builder/IndexBuilder.java | 13 +- .../IndexBuildingFailureException.java | 46 ++++ .../covered/CoveredColumnsIndexBuilder.java | 27 +- .../index/parallel/EarlyExitFailure.java | 42 +++ .../parallel/QuickFailingTaskRunner.java | 153 +++++++++++ .../write/ParallelWriterIndexCommitter.java | 100 +++---- 10 files changed, 623 insertions(+), 131 deletions(-) create mode 100644 src/main/java/com/salesforce/hbase/index/IndexBuildManager.java create mode 100644 src/main/java/com/salesforce/hbase/index/builder/IndexBuildingFailureException.java create mode 100644 src/main/java/com/salesforce/hbase/index/parallel/EarlyExitFailure.java create mode 100644 src/main/java/com/salesforce/hbase/index/parallel/QuickFailingTaskRunner.java diff --git a/src/main/java/com/salesforce/hbase/index/IndexBuildManager.java b/src/main/java/com/salesforce/hbase/index/IndexBuildManager.java new file mode 100644 index 00000000..6fa31e38 --- /dev/null +++ b/src/main/java/com/salesforce/hbase/index/IndexBuildManager.java @@ -0,0 +1,260 @@ +/******************************************************************************* + * Copyright (c) 2013, Salesforce.com, Inc. + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * + * Redistributions of source code must retain the above copyright notice, + * this list of conditions and the following disclaimer. + * Redistributions in binary form must reproduce the above copyright notice, + * this list of conditions and the following disclaimer in the documentation + * and/or other materials provided with the distribution. + * Neither the name of Salesforce.com nor the names of its contributors may + * be used to endorse or promote products derived from this software without + * specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" AND + * ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED + * WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE + * DISCLAIMED.

Helps for testing and also later adding other TaskRunners Additionally, formalizing Task/TaskBatch to support better failure policies. This way we can tie all the elements of the batch together and let the tasks determine if they want to fail together if another task fails in the same batch. We then also update the batch failure when we find a single task failure in the QuickFailing implementation. Additionally, this supports more complex task runners, for instance the task runner that would be needed for the TrackingParallelWriteIndexCommitter (not yet implemented as it would just be too much in the same patch --- .../hbase/index/IndexBuildManager.java | 14 ++-- .../com/salesforce/hbase/index/Indexer.java | 3 +- .../hbase/index/parallel/BaseTaskRunner.java | 55 ++++++++++++ .../parallel/QuickFailingTaskRunner.java | 57 ++++--------- .../salesforce/hbase/index/parallel/Task.java | 49 +++++++++++ .../hbase/index/parallel/TaskBatch.java | 84 +++++++++++++++++++ .../hbase/index/parallel/TaskRunner.java | 46 ++++++++++ .../write/ParallelWriterIndexCommitter.java | 13 ++- 8 files changed, 263 insertions(+), 58 deletions(-) create mode 100644 src/main/java/com/salesforce/hbase/index/parallel/BaseTaskRunner.java create mode 100644 src/main/java/com/salesforce/hbase/index/parallel/Task.java create mode 100644 src/main/java/com/salesforce/hbase/index/parallel/TaskBatch.java create mode 100644 src/main/java/com/salesforce/hbase/index/parallel/TaskRunner.java diff --git a/src/main/java/com/salesforce/hbase/index/IndexBuildManager.java b/src/main/java/com/salesforce/hbase/index/IndexBuildManager.java index 6fa31e38..209bf2bc 100644 --- a/src/main/java/com/salesforce/hbase/index/IndexBuildManager.java +++ b/src/main/java/com/salesforce/hbase/index/IndexBuildManager.java @@ -31,7 +31,6 @@ import java.util.ArrayList; import java.util.Collection; import java.util.List; -import java.util.concurrent.Callable; import java.util.concurrent.ExecutionException; import java.util.concurrent.LinkedBlockingQueue; import java.util.concurrent.ThreadPoolExecutor; @@ -53,6 +52,8 @@ import com.salesforce.hbase.index.builder.IndexBuildingFailureException; import com.salesforce.hbase.index.parallel.EarlyExitFailure; import com.salesforce.hbase.index.parallel.QuickFailingTaskRunner; +import com.salesforce.hbase.index.parallel.Task; +import com.salesforce.hbase.index.parallel.TaskBatch; /** * Manage the building of index updates from primary table updates. @@ -83,8 +84,6 @@ public class IndexBuildManager implements Stoppable { */ private static final String INDEX_BUILDER_KEEP_ALIVE_TIME_CONF_KEY = "index.builder.threads.keepalivetime"; - @SuppressWarnings("rawtypes") - private static final Callable[] EMPTY_CALLABLE_ARRAY = new Callable[0]; /** * @param newInstance @@ -147,7 +146,6 @@ private static ThreadPoolExecutor getDefaultExecutor(Configuration conf) { return pool; } - @SuppressWarnings("unchecked") public Collection> getIndexUpdate( MiniBatchOperationInProgress> miniBatchOp, Collection mutations) @@ -160,10 +158,10 @@ public Collection> getIndexUpdate( // fail lookups/scanning) and (2) by stopping this via the #stop method.

We ensure uniquness across servers by tagging on the RS name to the pool name.

This resolves the issue of salted indexes. Essentially, HTables have default pools with unbounded threads, but direct handoff of tasks via the queue. Therefore, the default of 1 thread meant that batching updates in a multi-threaded environment (or even to multiple RS) would cause a RejectedExecutionException. We up the value to Integer.MAX_VALUE by default, allowing us to grow as we need. This is not an ideal solution - it can quickly burst up to a large number of threads. What we really want to do is set a max level of parallelization and then queue up any remaining tasks (similar to what we are doing with the rest of the indexing pools). Additionally, we support the standard HTable retry values in a "set if not set" style so the user can override their settings. This means you have increased flexibility in how quickly you want an index update to fail, making it more resilient to RS (particularly the one holding -ROOT- and/or .META.) outage. --- .../index/parallel/ThreadPoolBuilder.java | 8 ++++---- .../index/table/CoprocessorHTableFactory.java | 19 ++++++++++++------- .../hbase/index/util/IndexManagementUtil.java | 6 ++++++ .../hbase/index/write/IndexWriter.java | 4 +++- .../hbase/index/write/IndexWriterUtils.java | 16 +++++++++++++--- 5 files changed, 38 insertions(+), 15 deletions(-) diff --git a/src/main/java/com/salesforce/hbase/index/parallel/ThreadPoolBuilder.java b/src/main/java/com/salesforce/hbase/index/parallel/ThreadPoolBuilder.java index e202f12c..fd160a4a 100644 --- a/src/main/java/com/salesforce/hbase/index/parallel/ThreadPoolBuilder.java +++ b/src/main/java/com/salesforce/hbase/index/parallel/ThreadPoolBuilder.java @@ -40,7 +40,7 @@ public class ThreadPoolBuilder { private static final Log LOG = LogFactory.getLog(ThreadPoolBuilder.class); private static final long DEFAULT_TIMEOUT = 60; - private static final int DEFAULT_MAX_THREADS = 1; + private static final int DEFAULT_MAX_THREADS = 1;// is there a better default?
