Lars Francke commented on HBASE-6513:
-------------------------------------
Found the issue. It's the tiebreaker in the SimpleRange class which isn't
breaking the tie because nanoTime apparently doesn't have a good enough
resolution on a Mac.
I've replaced the long with a UUID and it seems to work. I'll create a patch.
