Subject [jira] [Created] (HDFS-3688) Namenode loses datanode hostname if datanode re-registers
Date Thu, 19 Jul 2012 20:47:36 GMT
Jason Lowe created HDFS-3688:

             Summary: Namenode loses datanode hostname if datanode re-registers
                 Key: HDFS-3688
                 URL: https://issues.apache.org/jira/browse/HDFS-3688
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: data-node
    Affects Versions: 0.23.3
            Reporter: Jason Lowe

If a datanode ever re-registers with the namenode (e.g.: namenode restart, temporary network
cut, etc.) then the datanode ends up registering with an IP address as the datanode name rather
than the hostname.
