Summary: "Maintenance mode" master
Key: HBASE-21073
URL: https://issues.apache.org/jira/browse/HBASE-21073
Project: HBase
Issue Type: Sub-task
Components: amv2, hbck2, master
Reporter: stack
Assignee: stack
Make it so we can bring up a Master in "maintenance mode". This is parse of
master wal procs but not taking on regionservers. It would be in a state where
"repair" Procedures could run; e.g. a Procedure that could recover meta by
looking for meta WALs, splitting them, dropping recovered.edits, and even
making it so meta is readable. See parent issue for why needed (disaster
recovery).
