> In our ITBLL test we observer a race between the SCP and TRSP which causes a
> region being assigned to two region servers.
> Not fully understand the scenario, but anyway, the we do not consider the
> situation in the old code, that after SCP gets the region list of a dead
> server, there could still be a reportRegionStateTransition call from dead
> server and mess up things.
> In general, I think we should have a fence in the AssignmentManager to
> prevent the reportRegionStateTransition from the dead servers to mess up the
> states.
