> 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.
