--------------------------------------

             Summary: Views : Add URLConnectionProvider interface
                 Key: AMBARI-11516
                 URL: https://issues.apache.org/jira/browse/AMBARI-11516
             Project: Ambari
          Issue Type: Task
            Reporter: Tom Beerbower
            Assignee: Tom Beerbower
             Fix For: 2.1.0


Make an enhancement to view framework to expose a connection provider interface and make it available through the view context. This is being requested because the existing URLStreamProvider interface can only return a stream and does not provide any http error code or response body on failures.
Requested for TEZ view ...
The lack of this functionality makes it next to impossible to debug why a view is not working.
The tez view has hacks to reduce the message body for potential errors or treat an empty body as a 404.
For security errors, invalid hostnames/connection end points, etc. - instead of getting 401s/403s/connection timeouts/..., the UI ends up always showing a 404.
