Jimmy Xiang commented on HBASE-6272:
------------------------------------

That's a good question.  I am testing it on trunk now, so far so good.  As to 0.92 and 0.94, if the patch applies clean, I will just do some unit tests.
Otherwise, I will file a separate jira, do backport, and test it on a corresponding live cluster.

> AssignmentManger stores region state related information in several places: regionsInTransition, regions (region info to server name map), and servers (server name to region info set map).  However the access to these places is not coordinated properly.  It leads to inconsistent in-memory region state information.  Sometimes, some region could even be offline, and not in transition.
