Pankaj Kumar commented on HBASE-25447:
--------------------------------------
Discussed with [~Bo Cui] offline, reigon was stuck in RIT until there is HM
failover; since remoteProc is suspended due to OOM (unable to create new native
thread) while dispatching the proc.
Other chore services like CJ, QuotaObserverChore etc also failed with OOM.
However it is env problem, It's better to abort HMaster so that healthy standby
master will manage the HBase cluster operation after becoming active.
