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.
