Subject [jira] [Commented] (HBASE-9151) HBCK cannot fix when meta server znode deleted, this can happen if all region servers stopped and there are no logs to split.

-----------------------------------------------

I think this is the case that Anoop and me saw in a log for a testcase where the META got
assigned to a RS and there was only one RS that time.  So the META was hanging without assignment.

> When meta server znode deleted and meta in FAILED_OPEN state, then hbck cannot fix it.
This scenario can come when all region servers stopped by stop command and didnt start any
RS within 10 secs(with default configurations).
