Lars Hofhansl commented on HBASE-6537:
--------------------------------------

Hmm... There was no RegionStates in 0.94. (added in the ginormous HBASE-6272 patch)

> Appear in 94. trunk is ok for the issue
> Balancer will collect the regionplans to move(unassign and then assign).
> before unassign, disable table appears, 
> after close the region in rs, master will delete the znode, romove region from RIT,
> and then clean the region from the online regions.
> During romoving region from RIT and cleaning out the region from the online regions.

> balancer begins to unassign, it will get a NotServingRegionException and if the table
is disabling, it will deal with the state in master and delete the znode . However the table
is disabled now, so the RIT and znode will remain. TimeoutMonitor draws a blank on it.
> It will hold back enabling the table or balancer unless restart
