Subject [jira] [Commented] (HBASE-20178) [AMv2] Throw exception if hostile environment
Date Tue, 13 Mar 2018 18:00:00 GMT

stack commented on HBASE-20178:
-------------------------------

.005 cleanup the tablestate usage;  confusing (Class called TableState has enum State... and
statics to check which state... Make state checking more natural)

> New pattern where we throw exception on procedure construction if cluster is going down,
hosting master is stopping, table is offline, or table is read-only. Fail fast rather than
later internal to Procedure so can flag caller there is a problem.
> Changed Move/Split/Merge Procedures.
> No point queuing a move region for a table that is offline and which may never be re-enabled.
