> Separate out RM services into "Always On" and "Active"

> Key: YARN-1098

> Issue Type: Sub-task

>
> From discussion on YARN-1027, it makes sense to separate out services that
> are stateful and stateless. The stateless services can run perennially
> irrespective of whether the RM is in Active/Standby state, while the stateful
> services need to be started on transitionToActive() and completely shutdown
> on transitionToStandby().
> The external-facing stateless services should respond to the client/AM/NM
> requests depending on whether the RM is Active/Standby.
