> This stems from 2 issues:
> 1. the queryUri to find the driver http endpoint is missing a '/' after application ID.
> 2. YARN currently redirects the proxy call to the primary RM via a meta-refresh, which is not handled by our recovery mechanism assuming no redirects. See YARN-2605.
> 3. The driver does not recognize the evaluator trying to contact it and receives exception:
> {code}
> java.lang.RuntimeException: Contact from unknown Evaluator with identifier 'container_e02_1438245500443_0040_01_000004' with state 'RUNNING'
