Subject [jira] Commented: (HBASE-1243) oldlogfile.dat is screwed, so is it's region
Date Fri, 06 Mar 2009 21:21:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12679728#action_12679728
] 

stack commented on HBASE-1243:
------------------------------

I took a look. If no exception, it gets deleted higher up (its confusing -- logs used to be
run in HRegion, not in HStore).
