Subject [jira] [Created] (AMBARI-3622) [perf] Background operations dialog should not get all details of requests
Date Wed, 30 Oct 2013 13:21:25 GMT
Andrii Tkach created AMBARI-3622:

             Summary: [perf] Background operations dialog should not get all details of requests
                 Key: AMBARI-3622
             Project: Ambari
          Issue Type: Bug
          Components: client
    Affects Versions: 1.4.1
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
            Priority: Critical
             Fix For: 1.4.2

In Ambari UI we keep polling for last 10 requests, and *all* details about each request. 
On a 600 node cluster if you restart all services, this will contain MBs of data.

We do not need so much data just to show the number of operations. We need to request API
changes to provide rollup of tasks information into each request, and use that.

The polling query should look more like:
This should provide the following about request - 
* progress%
* completed (yes/no)
* state (success/warn/failure/timeout)

Users should open the background-operations dialog and see progress of requests without making
any further calls. Only when the user clicks on a request, should another call to get all
tasks information be done.
