[jira] [Created] (AMBARI-9800) 400-node cluster: Hosts page stuck in loading state

Andrii Babiichuk created AMBARI-9800:
----------------------------------------

             Summary: 400-node cluster: Hosts page stuck in loading state
                 Key: AMBARI-9800
                 URL: https://issues.apache.org/jira/browse/AMBARI-9800
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.0.0
            Reporter: Andrii Babiichuk
            Assignee: Andrii Babiichuk
            Priority: Critical
             Fix For: 2.0.0


Go to hosts page.
After loading hosts next request sent to server: /api/v1/clusters/c1?fields=Clusters/health_report,Clusters/total_hosts,alerts_summary_hosts&minimal_response=true
but it fails as "cancelled", UI sends request every 6 seconds, regardless whether previous was finished or not, so server can't response in time as if number of calls growing.
UI should make next call only when previous finished, should apply this approach to all pollings in ambari web to guarantee performance on big cluster.
