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

- I'm not very sure about giving multiple values in
hadoop.http.filter.initializers, have just seen it with
HttpCrossOriginFilterInitializer.
- Also please note that the configurations needs to be updated in all nodes
where the Tez client is used.
Will get back with more info on using multiple values in
hadoop.http.filter.initializers.
> 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?
