             Summary: ResourceManager and AdminService interact in a convoluted manner after YARN-1318
                 Key: YARN-1481
                 URL: https://issues.apache.org/jira/browse/YARN-1481
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Vinod Kumar Vavilapalli
            Assignee: Vinod Kumar Vavilapalli


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.
