Date Sun, 15 Jul 2012 18:59:34 GMT

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

@Ted, I was shutting down region servers, master, restarting them, while keeping moving regions
around. Any other mean things I should do to it?

> 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.
