> In HBASE-20700, we make RecoverMetaProcedure use a special lock which is only used by RMP to avoid dead lock with MoveRegionProcedure. But we will always schedule a RMP when master starting up, so we still need to make sure that there is no race between this RMP and other RMPs and SCPs scheduled before the master restarts.
