---------------------------------------
What do you see as the mechanism for relating this state? API, REST, JMX?

> Yarn Application state is different than the application state as perceived by Yarn. Such as:
> * When Yarn app state says RUNNING, the application deployed by Slider may actually be in the process of starting, and not yet ready for clients.
> * When Yarn app state says RUNNING, the application may in fact be unhealthy as in the component instances have gone down and waiting to come back up
> Application should be allowed to define its state (for its admin and clients) that is different than the application state as reported by Yarn.
