Jimmy Xiang commented on HBASE-7083:
------------------------------------
At first, there won't be double assignment since currently, the region will be
closed if it is indeed open (HBASE-6611). In this scenario, it is open on the
dead region server, so no double assignment for sure. Since it is on the dead
server, SSH should fix it. However, it can't since the region is not in meta.
That's probably a scenario cooked up in the unit test. In the unit test, the
daughter is open and good. The meta entry is removed intentionally.
In real cluster, it may probably not happen. However, force-assign is safe,
just in case.
