stack updated HBASE-14883:
--------------------------
Attachment: 14883-branch-1.txt
Remove balance assert on end of test. Just do assert that no RIT. Thats what
the test is about, not about balancing. Balance is being used to assert no
RIT.. just cut to the chase. Table is being removed on end of test anyways so
balance is just work.
