Yusaku Sako updated AMBARI-3087:
--------------------------------

    Description: 
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 when a server died and killed all the hosted VMs.
