Date Wed, 12 Oct 2011 00:53:11 GMT
Create some invalid zk nodes when a clean cluster start.
--------------------------------------------------------

                 Key: HBASE-4580
                 URL: https://issues.apache.org/jira/browse/HBASE-4580
             Project: HBase
          Issue Type: Bug
          Components: master
    Affects Versions: 0.92.0
            Reporter: gaojinchao
             Fix For: 0.92.0


The below logs said that we created a invalid zk node when restarted a cluster.
it mistakenly believed that the regions belong to a dead server.
