Xi Wang created AMBARI-3087:
-------------------------------

             Summary: Ambari dashboard does not update when datanodes are lost
                 Key: AMBARI-3087
                 URL: https://issues.apache.org/jira/browse/AMBARI-3087
             Project: Ambari
          Issue Type: Bug
          Components: client
    Affects Versions: 1.4.0
            Reporter: Xi Wang
            Assignee: Xi Wang
             Fix For: 1.4.0


When a host goes offline completely, Ambari will not update the dashboard to reflect the loss
of the datanode. Attached is a screenshot of the dashboard  showing 8/8 active DNs, whereas
the HDFS service page shows 6/8.

This happened on sedemo when a server died and killed all the hosted VMs.
