Nate Putnam commented on HBASE-5922:
------------------------------------
@Anoop
Agreed that the <= is probably the right thing to do. I dug into that piece of
code and think there is some issue with the underlying KeyValue.comparator that
will keep that from working. It seems that it's nearly impossible for key to
exactly equal splitkey.
This particular issue is a production blocker for us so I would like to get the
current fix into the code base and file another issue for the splitkey equality
work. Sound good?
