Hudson commented on HBASE-14954: -------------------------------- FAILURE: Integrated in HBase-1.2 #432 (See [https://builds.apache.org/job/HBase-1.2/432/]) HBASE-14954 IllegalArgumentException was thrown when doing online (tedyu: rev f4fec4cd13043c8d50e2bd063903269382a6306f) * hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestCompactSplitThread.java * hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/CompactSplitThread.java > IllegalArgumentException was thrown when doing online configuration change in > CompactSplitThread > ------------------------------------------------------------------------------------------------ > > Key: HBASE-14954 > URL: https://issues.apache.org/jira/browse/HBASE-14954 > Project: HBase > Issue Type: Bug > Components: Compaction, regionserver > Affects Versions: 1.1.2 > Reporter: Victor Xu > Assignee: Victor Xu > Fix For: 2.0.0, 1.2.0, 1.3.0, 1.1.3 > > Attachments: HBASE-14954-v1.patch > > > Online configuration change is a terrific feature for HBase administrators. > However, when we use this feature to tune compaction thread pool size online, > it triggered a IllegalArgumentException. The cause is the order of > setMaximumPoolSize() and setCorePoolSize() of ThreadPoolExecutor: when > turning parameters bigger, we should setMax first; when turning parameters > smaller, we need to setCore first. Besides, there is also a copy-code bug in > merge and split thread pool which I will fix together. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
