Duo Zhang commented on HBASE-20881:
-----------------------------------
I believe there are still some bugs, maybe around unassign the regions when
deleting a table, but it is hard to catch as we can not see the full log in pre
commit result. Maybe we could push it to master first and then focus on the
flaky dashboard to fix the problems.
> 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...
