Subject [jira] [Updated] (HBASE-4842) [hbck] Fix intermittent failures on TestHBaseFsck.testHBaseFsck
Date Mon, 21 Nov 2011 22:31:45 GMT

     [ https://issues.apache.org/jira/browse/HBASE-4842?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Hsieh updated HBASE-4842:
----------------------------------

    Description: 
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.
