             Summary: Ambari web should display the error message when there is server error. 
                 Key: AMBARI-3133
                 URL: https://issues.apache.org/jira/browse/AMBARI-3133
             Project: Ambari
          Issue Type: Task
          Components: client
    Affects Versions: 1.4.1
            Reporter: Jaimin D Jetly
            Assignee: Jaimin D Jetly
             Fix For: 1.4.1


We display error message for a server error while installer wizard. Similarly we should display error message for main application.
As a part of this ticket, we add error-handling function in ajax.js and http_client.js utility files that displays appropriate message for server error.
There are certain operations/API calls that do not go through ajax.js (wrapper over all api calls) or http_client.js (used for apis doing constant polling). This error callback function won't be invoked for those operations.
