----------------------------------------
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.
