> For the below spec, the service will not stop even after container failures because of the NM auto retry properties :
>  * "yarn.service.container-failure.retry.max": 1,
>  * "yarn.service.container-failure.validity-interval-ms": 5000
>  The NM will continue auto-restarting containers.
>  {{fail_after 20}} fails after 20 seconds. Since the validity failure interval is 5 seconds, NM will auto restart the container.

> If {{restart_policy}} is NEVER, then the service should stop after the container fails.
> Since we have introduced, the service level Restart Policies, I think we should make the NM auto retry configurations part of the {{RetryPolicy}} and get rid of all {{yarn.service.container-failure.**}} properties. Otherwise it gets confusing.
