stack commented on HBASE-4382:
------------------------------
I think you are looking hashcode vs encoded name. See
http://hbase.apache.org/xref/org/apache/hadoop/hbase/HRegionInfo.html#357
> Region encoded name is hash of tablename + start key + regionid (timestamp);
> should include end key when hashing.

> Seems odd that region encoded name is same for regions if made in same second
> with same start key tough their end keys are different. It can happen in
> unit test. Should mix in the end key when coming up w/ the region name
> encoded name.
