> Its seems that on the 0.92 branch in particular, TestHBaseFsck.testHBaseFsck is intermittently
failing.
> In the test, a region's assignment is purposely changed in META but not in ZK.  After
the equivalent of 'hbck -fix', a subsequent check that should be clean comes up with a new
ZK assignment but with META still being inconsistent with ZK.  The RS in ZK sometimes this
points to the same RS, but sometimes it "moves" to another ZK.
