> Key: YARN-2974
> URL: https://issues.apache.org/jira/browse/YARN-2974
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: webapp
> Affects Versions: 2.6.0
> Reporter: Steve Loughran
>
> The Jersey {{ErrorMessagesException}} supports a list of messages, and is how
> jersey itself builds up errors.
> {{GenericExceptionHandler }} doesn't have special handling here and converts
> to a 500, discarding all the text as it does so.
> the handler should recognise the exception, log the messages and build up the
> response text from it.
