> Currently we just call openRegion and closeRegion directly, which is a bit buggy. For example, in order to not fail all the open region requests while there is only one failure, we will catch the exception and set a flag in the return value. But for executeProcedures call, the return value will be ignored, and we expect the openRegion method will always call reportRegionStateTransition to report the failure but in fact it does not...
> And after HBASE-20881, we can confirm that the race could happen, where we send a close request to a region which is opening(HBASE-21199), and vice visa. So I think here we need to revisit the implementation of executeProcedures to make it more stable.
