> Internal meta region state could be corrupted if the meta is not on master:
> 1. the meta region server (not master) shuts down,
> 2. meta SSH offlines it without updating the dead server's region list,
> 3. meta is transitioned to pending_open and the previous server (the dead server) of meta is lost,
> 4. meta is assigned somewhere else without updating its previous server,
> 5. normal SSH processes the dead server and offlines all of it's dead regions including the meta, so the meta internal state is corrupted
