[jira] [Created] (AMBARI-23978) Express Upgrade: Clicking on upgrade item shows no tasks on large clusters

Andrii Tkach created AMBARI-23978:
-------------------------------------

             Summary: Express Upgrade: Clicking on upgrade item shows no tasks on large clusters
                 Key: AMBARI-23978
                 URL: https://issues.apache.org/jira/browse/AMBARI-23978
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.7.0
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
             Fix For: 2.7.0


There are two issues over here.
*1st issue:*
This seems to be a functional bug. As it seems from the attached screenshot that even after API call was completed content was not rendered [^Timing_call_completed.png]

*2nd issue:*
There seems to be a performance issue. UI asks for all tasks fields ([^API_Signature.png]) instead of only ones that are needed making api call really expensive. Expected behavior is that only status should be asked for and when user clicks on a task then  log for that task should be requested.
