Subject [jira] [Created] (AMBARI-2670) Start button not available for various components within 10 sec after BG operation [stop] finish
Date Wed, 17 Jul 2013 15:20:49 GMT
Antonenko Alexander created AMBARI-2670:
-------------------------------------------

             Summary: Start button not available for various components within 10 sec after
BG operation [stop] finish
                 Key: AMBARI-2670
                 URL: https://issues.apache.org/jira/browse/AMBARI-2670
             Project: Ambari
          Issue Type: Bug
          Components: client
    Affects Versions: 1.2.5
            Reporter: Antonenko Alexander
            Assignee: Antonenko Alexander
             Fix For: 1.2.5


Steps to reproduce: 
1. Stop a component. 
2. Wait for the corresponding BG operation to finish. 
Result: 
"Start" button isn't available for the component within 10 seconds since stop operation finished
in UI. It appears later.

This happens cuz of update interval, it is set to 15 seconds (App.contentUpdateInterval),
that`s why in some moments it can take up to 15 sec to update components status, after request
is done.

Solution: Create a seperate update interval specialy for updating host components. In config.js
we even have App.componentsUpdateInterval = 6000; But this value was not used anywhere in
code till now.
