Subject [jira] [Commented] (HBASE-6028) Implement a cancel for in-progress compactions
Date Wed, 13 Jun 2012 18:58:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6028?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13294619#comment-13294619
] 

Nicolas Spiegelberg commented on HBASE-6028:
--------------------------------------------

this should be trivial to implement.  just remember that canceling a compaction also requires
manually freeing the files under compaction.

> Depending on current server load, it can be extremely expensive to run periodic minor
/ major compactions.  It would be helpful to have a feature where a user could use the shell
or a client tool to explicitly cancel an in-progress compactions.  This would allow a system
to recover when too many regions became eligible for compactions at once
