[jira] [Commented] (HBASE-6679) RegionServer aborts due to race between compaction and split

    [ https://issues.apache.org/jira/browse/HBASE-6679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13443568#comment-13443568 ] 

Ted Yu commented on HBASE-6679:
-------------------------------

Looks like we need some locking mechanism to make compacting and splitting the same region mutually exclusive.

> In our nightlies, we have seen RS aborts due to compaction and split racing. Original parent file gets deleted after the compaction, and hence, the daughters don't find the parent data file. The RS kills itself when this happens. Will attach a snippet of the relevant RS logs.
