> TestAssignmentManager#testBalance() fails pretty frequently on CentOS 5 for 0.94. The
root cause is that ClosedRegionHandler is executed by an executor, and before it finishes,
the region transition is done for OPENING and OPENED.
> This seems to be just a test problem, not an actual bug, since the region server won't
open the region unless it get's it from the assign call on ClosedRegionHandler.process().

> I've seen that HBASE-6109 has a fix for this already, will just backport those changes.
This is 0.94 only.
