-------------------------------
Oh, may need to do same for hbase:namespace.
> [hbck2] Queue an assign of hbase:meta
> -------------------------------------
>
> Key: HBASE-21156
> URL: https://issues.apache.org/jira/browse/HBASE-21156
> Project: HBase
> Issue Type: Sub-task
> Components: hbck2
> Affects Versions: 2.1.0
> Reporter: stack
> Assignee: stack
> Priority: Major
> Fix For: 2.1.1
>
>
> 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).
