Jimmy Xiang commented on HBASE-7335:
------------------------------------

This region should be a daughter region.  The region split should be succeeded. 
It looks to me the parent region is removed while there are still daughter 
regions refer to it.  Since the parent region is gone, we got no choice and 
have to remove the reference file.

Do you have any data loss?
