stack commented on HBASE-21745:
-------------------------------
HBASE-22680 adds offline rebuild of meta for hbase2 to hbck2. Over in
HBASE-22567, I've added note on how I think the OfflineMetaRepair update and
the work in HBASE-22567 compliment each other.
> Make HBCK2 be able to fix issues other than region assignment
