-----------------------------------
Let me commit. [~stack] Let's also commit HBASE-20881 to branch-2? So that the
fix here could also go into branch-2.
Thanks.

> For TRSP, and also RTP in branch-2.0 and branch-2.1, if we fail to assign or
> unassign a region, we will set the procedure to WAITING_TIMEOUT state, and
> rely on the ProcedureEvent in RegionStateNode to wake us up later. But after
> restarting, we do not suspend the ProcedureEvent in RSN, and also do not add
> the procedure to the ProcedureEvent's suspending queue, so we will hang there
> forever as no one will wake us up.
