Bikas Saha commented on YARN-1098:
----------------------------------
Patch looks good to me. Karthik, can you please rebase the patch wrt YARN-1107
so that we can commit this. Thanks!
Unrelated. Why are the secret manager not services themselves? If they were we
wouldnt have to handle them separately in start and stop.
> Separate out RM services into "Always On" and "Active"

> 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.
