Subject [jira] [Updated] (AMBARI-6532) Error message appears after last step of Enable security, NameNode HA and Add Service wizard
Date Thu, 17 Jul 2014 23:46:05 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-6532?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jaimin D Jetly updated AMBARI-6532:
-----------------------------------

    Description: 
*STR:*
1) Deploy cluster
2) Go through either security, Add Service or Enable NameNode HA
2) Go to the final step of the wizard
3) Click 'Done'

*Actual result:* After clicking 'Done' there is modal window with next message: "Error in
persisting web client state at ambari server: Error 0" 

After that Ambari works correctly, but once other browser opens UI (or do logout/login), last
step of the wizard appears again.  Probably, it is consequence from described issue.

*Reason:*
The calls for user preferences are made asynchronous lately. App.clusterStatus.setClusterStatus
function that used App.userPref mixin's postUserPref method was made asynchronous. App.clusterStatus.setClusterStatus
function is normally called at the end of the wizard to state to the server persist key that
wizard is completed and then window.location.reload() function is called. As the prior call
was changed to asynchronous, browser window was reloaded before the client even successfully
submitted the Ajax call and the web state of the wizard completion was not saved on the server.
