             Summary: Warn message about httpshuffle in NM logs
                 Key: MAPREDUCE-5763
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5763
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Sandy Ryza

{code}
2014-02-20 12:08:45,141 WARN org.apache.hadoop.yarn.server.nodemanager.containermanager.AuxServices: The Auxilurary Service named 'mapreduce_shuffle' in the configuration is for class class org.apache.hadoop.mapred.ShuffleHandler which has a name of 'httpshuffle'. Because these are not the same tools trying to send ServiceData and read Service Meta Data may have issues unless the refer to the name in the config.
2014-02-20 12:08:45,142 INFO org.apache.hadoop.yarn.server.nodemanager.containermanager.AuxServices: Adding auxiliary service httpshuffle, "mapreduce_shuffle"
{code}

I'm seeing this in my NodeManager logs,  even though things work fine.  A WARN is being caused by some sort of mismatch between the name of the service (in terms of org.apache.hadoop.service.Service.getName()) and the name of the auxiliary service.
