Description

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.
