Ted Yu commented on HBASE-4927:
-------------------------------

Also ran through the two tests in original patch:
{code}
 1302  mt -Dtest=TestHRegionInfo
 1303  mt -Dtest=TestCatalogJanitor
{code}
They passed as well.

Integrated to 0.92 and TRUNK.

Thanks for the addendum, Jimmy.

Thanks for the help, Jonathan.

> When reviewing HBASE-4238 backporting, Jon found this issue.
> What happens if the split points are  (empty end key is the last key, empty start key is the first key)
> Parent     [A,)
> L daughter [A,B), 
> R daughter [B,)
> When sorted, we gets to end key comparision which results in this incorrector order:
> [A,B), [A,), [B,) 
> we wanted:
> [A,), [A,B), [B,)
