---------------------------------------

             Summary: Datanode should use hostname in place of ip addresses to allow DN's to work when ipaddress change
                 Key: HDDS-1933
                 URL: https://issues.apache.org/jira/browse/HDDS-1933
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Datanode, SCM
    Affects Versions: 0.4.0
            Reporter: Mukul Kumar Singh


This was noticed by [~elek] while deploying Ozone on Kubernetes based environment.

When the datanode ip address change on restart, the Datanode details cease to be correct for the datanode. and this prevents the cluster from functioning after a restart.
