Karthik Kambatla updated YARN-1098:
-----------------------------------
Attachment: yarn-1098-approach.patch
Attaching a first-cut patch that separates out the services using approach 2
from my earlier comment. It doesn't work yet - working on issues with some
dependencies.
Appreciate any early feedback on whether the approach makes any sense in the
first place.
> Separate out stateless services from stateful services in the RM

> From discussion on YARN-1027, it makes sense to separate out services that
> are stateful and stateless. The stateless services can be HA-agnostic and be
> run perennially irrespective of whether the RM is in Active/Standby state,
> while the stateful services need to be aware of HA and be started on
> transitionToActive() and completely shutdown on transitionToStandby().
