Benoy Antony created HDFS-7303:
----------------------------------

             Summary:  If there are multiple datanodes on the same host, then only one datanode is listed on the NN UI’s datanode tab
                 Key: HDFS-7303
                 URL: https://issues.apache.org/jira/browse/HDFS-7303
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.5.1
            Reporter: Benoy Antony
            Assignee: Benoy Antony
            Priority: Minor


If you start multiple datanodes on different ports on the the same host, only one of them appears in the NN UI’s datanode tab.

While this is not a common scenario, there are still scenarios where you need to start multiple datanodes on the same host.
