-------------------------------------------------------------
Attached a patch which checks if any region is still in transition (in the
region server side) before getting the online region list. If there is a
region in transition, it means the region hasn't been moved to the online
region set yet after the znode is moved to OPEN. If that's the case, that
explains why this test is rare to fail.
