Hudson commented on HBASE-18375: -------------------------------- FAILURE: Integrated in Jenkins build HBase-2.0 #467 (See [https://builds.apache.org/job/HBase-2.0/467/]) HBASE-18375: Fix the bug where the pool chunks from ChunkCreator are (anastas: rev 68ec2a9da022f7824e9a45ef89a0c4b8bcb838f3) * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/ChunkCreator.java * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/CompactingMemStore.java * (edit) hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestMemstoreLABWithoutPool.java * (edit) hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestMemStoreLAB.java * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/CompactionPipeline.java * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/MemStoreLABImpl.java > The pool chunks from ChunkCreator are deallocated while in pool because there > is no reference to them > ----------------------------------------------------------------------------------------------------- > > Key: HBASE-18375 > URL: https://issues.apache.org/jira/browse/HBASE-18375 > Project: HBase > Issue Type: Sub-task > Affects Versions: 2.0.0-alpha-1 > Reporter: Anastasia Braginsky > Assignee: Anastasia Braginsky > Priority: Critical > Fix For: 2.0.0 > > Attachments: HBASE-18375-branch-2.patch, HBASE-18375-V01.patch, > HBASE-18375-V02-branch-2.patch, HBASE-18375-V02.patch, HBASE-18375-V03.patch, > HBASE-18375-V04.patch, HBASE-18375-V05.patch, HBASE-18375-V06.patch, > HBASE-18375-V07.patch, HBASE-18375-V08.patch, HBASE-18375-V09.patch, > HBASE-18375-V10.patch, HBASE-18375-V11.patch > > > Because MSLAB list of chunks was changed to list of chunk IDs, the chunks > returned back to pool can be deallocated by JVM because there is no reference > to them. The solution is to protect pool chunks from GC by the strong map of > ChunkCreator introduced by HBASE-18010. Will prepare the patch today. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
