             Summary: Hosts page responsiveness is severely impacted when metrics API responses are slow
                 Key: AMBARI-11992
                 URL: https://issues.apache.org/jira/browse/AMBARI-11992
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.1.0
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
            Priority: Critical
             Fix For: 2.1.0


We've seen that the Hosts page loads very slowly when metrics API calls are responding slowly. Under this condition, shutting down AMS makes the Hosts page responsive again.
We should make Hosts page responsiveness independent of metrics API call latency by loading non-metric data and rendering the page first, and then lazy loading metrics info.
