Default RPC handlers are very low for YARN servers
--------------------------------------------------

                 Key: MAPREDUCE-3699
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3699
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.0
            Reporter: Vinod Kumar Vavilapalli
             Fix For: 0.23.1


Mainly NM has a default of 5, RM has 10 and AM also has 10 irrespective of num-slots, num-nodes and num-tasks respectively. Though ideally we want to scale according to slots/nodes/tasks, for now increasing the defaults should be enough.
