[jira] Commented: (HBASE-917) filesystem intensive operations such as compaction should be load aware

["Billy Pearson (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-917?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12638513#action_12638513 ] 

Billy Pearson commented on HBASE-917:
-------------------------------------

I see my compaction stop now during a long insert jobs that is loading the server vary heavy.
I thank it related to HBASE-616 but I do not get any messages from in the logs as we see from HBASE-616
Once insert load slows the next memcache flush starts a compaction.

> If the underlying filesystem is already severely stressed, running intensive operations such as compaction is asking for trouble. Ideally, such actions should be deferred until load is observed to lessen.
