Todd Johnson commented on HBASE-5922:
-------------------------------------
Yeah, that's not how it seems to me. But then, I didn't write the code
originally, so perhaps I misunderstand it.
We added a test case that causes infinite recursion with the old code, but
appears to work with the patch. The test case searches for a key that is not
equal to the split key. Given this, I don't see how the equals check could be
the problem.
