> [hbck] Fix intermittent failures on TestHBaseFsck.testHBaseFsck
> ---------------------------------------------------------------
>
> Key: HBASE-4842
> URL: https://issues.apache.org/jira/browse/HBASE-4842
> Project: HBase
> Issue Type: Bug
> Reporter: Jonathan Hsieh
>
> 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.
