> We need this to effect repair when damage.
> If procedure WALs AND a server WAL dir are lost or cleaned or we crashed during partial split (unlikely scenarios but nonetheless possible), a Master can be stuck unable to become active because there is no assign procedure for hbase:meta in the system.
> The reasonable argument over in HBASE-21035 has it that attempts at auto-repair under these extremes could cause other issues so at least until we learn more, we for now punt to the operator for fix-up.
> To reproduce the catastrophe, see notes in HBASE-21035 (and [~allan163]'s test).
