> 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

> [A,B), [A,), [B,)
> we wanted:
> [A,), [A,B), [B,)
