Duo Zhang commented on HBASE-20881:
-----------------------------------
It seems that the 'kill before update ' is too aggressive and cause TRSPs can
not be finished if there are more than 1 regions need to be assigned or
uassigned...
Let me change the UT. For the old RIT procedure, it will loop inside the
execute method so it will not crash between states...
> Introduce a region transition procedure to handle all the state transition
> for a region

> Now have an AssignProcedure, an UnssignProcedure, and also a
> MoveRegionProcedure which schedules an AssignProcedure and an
> UnssignProcedure to move a region. This makes the logic a bit complicated, as
> MRP is not a RIT, so when SCP can not interrupt it directly...
