Description

Currently log is coming like following..

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.

Since get class will return class as prefix,, we no need keep "class" in log..

Class<? extends AuxiliaryService> sClass = conf.getClass(
              String.format(YarnConfiguration.NM_AUX_SERVICE_FMT, sName), null,
              AuxiliaryService.class);
