Subject [jira] [Commented] (HBASE-17174) Use shared threadpool in BufferedMutatorImpl
Date Thu, 24 Nov 2016 17:18:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17174?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15693814#comment-15693814
] 

Ted Yu commented on HBASE-17174:
--------------------------------

{code}
204	          terminated = this.pool.awaitTermination(60, TimeUnit.SECONDS);
{code}
How about calling pool.shutdowNow() in the case of timeout ?

Is there some statistics showing the benefit of this change ?

Thanks

> A update-heavy application, for example, loader, creates many BufferedMutator for batch
updates. But these BufferedMutators can’t share a large threadpool because the shutdown()
method will be called when closing any BufferedMutator. This patch adds a flag into BufferedMutatorParams
for preventing calling the shutdown() method in BufferedMutatorImpl#close
