> In MergeTableRegionsProcedure, we issue UnassignProcedures to offline regions
> to merge. But if we restart master just after MergeTableRegionsProcedure
> finished these two UnassignProcedure and before it can delete their meta
> entries. The new master will found these two region is CLOSED but no
> procedures are attached to them. They will be regard as RIT regions and
> nobody will clean the RIT state for them later.
> A quick way to resolve this stuck situation in the production env is
> restarting master again, since the meta entries are deleted in
> MergeTableRegionsProcedure. Here, I offer a fix for this problem.
