[jira] [Created] (AMBARI-17063) Retrieve specific metrics when Ambari queries NameNode HA states

Andrew Onischuk created AMBARI-17063:
----------------------------------------

             Summary: Retrieve specific metrics when Ambari queries NameNode HA states
                 Key: AMBARI-17063
                 URL: https://issues.apache.org/jira/browse/AMBARI-17063
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 2.4.0
         Attachments: AMBARI-17063.patch

This is a follow-on jira of BUG-53459: when Ambari queries NameNode's HA
states, currently it retrieves a group of metrics including some unnecessary
ones that may compete for NameNode lock. It would be better for Ambari to only
retrieve HA state metrics from NameNode.
