Subject [jira] [Commented] (HBASE-13560) Large compaction queue should steal from small compaction queue when idle
Date Sun, 31 May 2015 01:27:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13560?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14566284#comment-14566284
] 

Changgeng Li commented on HBASE-13560:
--------------------------------------

it should always be running. That's only for unit test purpose because originally the test
was to verify the small compaction queue, and the newly introduced change would make large
thread pool steal the jobs and will break this test. So this line is to disable the large
compaction thread pool so that it won't steal jobs.

> If you tune compaction threads so that a server is never over commited when large and
small compaction threads are busy then it should be possible to have the large compactions
steal work.
