Siddharth Wagle created AMBARI-13641:
----------------------------------------

             Summary: Various metrics show no data available - when HA enabled
                 Key: AMBARI-13641
                 URL: https://issues.apache.org/jira/browse/AMBARI-13641
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.1.2
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
            Priority: Critical
             Fix For: 2.1.3


The Metrics Cache introduced in Ambari stores the metrics result in an HashMap with metric
name as the key, this results in a problem when the same request needs to fetch metrics for
both the Namenodes or both the Resourcemangers. The last result gets cached.

*Note*: Workaround for this is to disable cache in 2.1.2 by setting this property in ambari.properties
file : server.timeline.metrics.cache.disabled = true
