Subject [jira] [Commented] (HBASE-8040) Race condition in AM after HBASE-7521 (only 0.94)
Date Fri, 08 Mar 2013 11:28:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8040?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13597033#comment-13597033

ramkrishna.s.vasudevan commented on HBASE-8040:

Can you take a look at  this patch.  Atleast tries to avoid the problem by comparing the timestamp
between the previous OFFLINE state and the new one if updated.
But the change in OpenRegionHandler is surely needed otherwise if openRegion fails, transitiontoFailedOpen
will be done twice (but second time it will fail in finally block).
I think i missed out this when HBASE-7698.

Pls take a look and suggest what you feel.
