> Yarn enforces these two checks:
> 1. ANY_HOST requests should always be made with relax-locality = true
> 2. A request with relax-locality = false should not be in the same priority as another with relax-locality = true
> Since the Samza AM makes preferred-host requests with relax-locality = false, it follows that ANY_HOST requests should specify a different priority-level. We can safely set priority of preferred-host requests to be higher than any-host requests since data-locality is critical.
