             Summary: Extend visualization for Maintenance Mode under Datanode tab in the NameNode UI
                 Key: HDFS-11265
                 URL: https://issues.apache.org/jira/browse/HDFS-11265
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: 3.0.0-alpha1
            Reporter: Manoj Govindassamy



With HDFS-9391, DataNodes in MaintenanceModes states are shown under DataNode page in NameNode UI, but they are lacking icon visualization like the ones shown for other node states. Need to extend the icon visualization to cover Maintenance Mode.

<script type="text/x-dust-template" id="tmpl-datanode">
<div class="page-header"><h1>Datanode Information</h1></div>
<div>
  <ul class="dfshealth-node-legend">
    <li class="dfshealth-node-icon dfshealth-node-alive">In service</li>
    <li class="dfshealth-node-icon dfshealth-node-down">Down</li>
    <li class="dfshealth-node-icon dfshealth-node-decommissioned">Decommissioned</li>
    <li class="dfshealth-node-icon dfshealth-node-down-decommissioned">Decommissioned &amp; dead</li>
  </ul>
</div>
