Jonathan Hsieh updated HBASE-4842:
----------------------------------
Attachment: hbase-4842.patch
With this patch, I add a 1s delay between 'hbck -fix' and 'hbck'. The test new
seems to pass consistently (ran 20x).

> 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.
