Date Tue, 20 Dec 2016 23:01:58 GMT
Aravindan Vijayan created AMBARI-19261:
------------------------------------------

             Summary: AMS cannot start after NN HA is enabled due to hbase.rootdir pointing
to Standby NN
                 Key: AMBARI-19261
                 URL: https://issues.apache.org/jira/browse/AMBARI-19261
             Project: Ambari
          Issue Type: Bug
          Components: ambari-metrics
    Affects Versions: 2.5.0
            Reporter: Aravindan Vijayan
            Assignee: Aravindan Vijayan
            Priority: Critical
             Fix For: 2.5.0


BUG
Stack advisor never updates the hbase.rootdir for NN HA deployment.

So AMS was pointing to standby NN instead of nameservice resulting in :
