Karthik Kambatla updated YARN-1098:
-----------------------------------
Attachment: yarn-1098-1.patch
Uploading a patch along the lines of my previous commit.
The only change is that AdminService is also in the Active services. We should
move it to "Always On" once we make it HA-aware; currently, some of the
functions don't apply to Standby RM.
Also, the patch depends on HADOOP-9918.
> 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.
