Subject [jira] [Commented] (HBASE-5857) RIT map in RS not getting cleared while region opening
Date Mon, 23 Apr 2012 15:13:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5857?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13259649#comment-13259649

stack commented on HBASE-5857:

@Chinna Good find.  Nice use of Mockito Whitebox too.  Does your test confirm the fix though?
 Maybe I'm not reading it right.  Should it check the regionserver instance does not have
the test region in its this.regionsInTransitionInRS Map?  Thanks.

> While opening the region in RS after adding the region to regionsInTransitionInRS if
tableDescriptors.get() throws exception the region wont be cleared from regionsInTransitionInRS.
So next time if it tries to open the region in the same RS it will throw the RegionAlreadyInTransitionException.
> if swap the below statement this issue wont come.
> {code}
> this.regionsInTransitionInRS.putIfAbsent(region.getEncodedNameAsBytes(),true);
> HTableDescriptor htd = this.tableDescriptors.get(region.getTableName());
