Sergey Shelukhin commented on HBASE-8219:
-----------------------------------------

bq. (It could be caused if one merging region's range contains another's)
Is it a legal condition?

> After HBASE-7403 we now have two different tools for online and offline merge, and the
result produced by the two are different. (the online one works with snapshots, the offline
not)
> We should remove the offline one, or align it to the online code.
> Most of the offline code in HRegion.merge() can be replaced with the one in RegionMergeTransaction,
used by the online version.
