Subject [jira] [Commented] (HBASE-12005) Split/merge fails if master restarts before PONR
Date Thu, 18 Sep 2014 21:54:33 GMT

Jimmy Xiang commented on HBASE-12005:
-------------------------------------

No problem. Instead of persisting these transient states, attached a patch that re-creates
them.

> This applies to RPC based assignment. The root cause is that we don't persist the state
of the new region(s). If we do persist it, we need to clean it up if the split/merge fails.
