-----------------------------
Summary: [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
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).
