stack commented on HBASE-8145:
------------------------------
I have fix coming in hbase-7905 If null key, skips the row in the test. In
general null row should fail fast. It just took a while weeding out all usages
in tests (I think I have it now over in hbase-7905)
> TestHCM flaky: java.lang.IllegalArgumentException: Row length is 0

> We're likely to get sometimes the startKey of the first region here, and
> that's an empty byte array. This make the put creation to fail, since there
> is now (with HBASE-8101) a check on the empty rows at put creation.
