Aman Poonia commented on HBASE-30169:
-------------------------------------
[~umesh9414] If a region is not in terminal state we say it is still in
transition. The region you showed is surely a parent but it should not be in
CLOSING state. It should be in CLOSED state. If we don't count it as RIT how
would we ever know if this has moved to CLOSED?
> Split completed parent region added to RIT list on host RS and master crash
