[jira] [Created] (TEZ-3488) Tez UI Vertex 404

George Liaw created TEZ-3488:
--------------------------------

             Summary: Tez UI Vertex 404
                 Key: TEZ-3488
                 URL: https://issues.apache.org/jira/browse/TEZ-3488
             Project: Apache Tez
          Issue Type: Bug
    Affects Versions: 0.8.4
            Reporter: George Liaw


When we're trying to view vertices for a running job, the Vertex page will show a 404 error saying:
"Could not retrieve expected data from @ <url>"
And the Vertex Counter page will show:
"Counters unavailable"
and
"Error code: Unknown, message: Resource Manager (RM) out of reach. Either it's down or CORS is not enabled"

The RMs are up and CORS is enabled. If we go to the displayed url, we get the expected XML with the application info. When the DAG finishes running, those errors go away and the pages display fine. Any idea what's going on here?
