> This is something I found while reviewing YARN-1318, but didn't halt that patch as many
cycles went there already. Some top level issues
>  - Not easy to follow RM's service life cycle
>     -- RM adds only AdminService as its service directly.
>     -- Other services are added to RM when AdminService's init calls RM.activeServices.init()
>  - Overall, AdminService shouldn't encompass all of RM's HA state management. It was
originally supposed to be the implementation of just the RPC server.
