                 Key: MAPREDUCE-3115
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3115
             Project: Hadoop Map/Reduce
          Issue Type: Bug
         Environment: NA
            Reporter: Bhallamudi Venkata Siva Kamesh


When we set the value for the property *mapred.map.multithreadedrunner.class* as instance of MultithreadedMapper, using MultithreadedMapper.setMapperClass(), it simply throws IllegalArgumentException.
But when we set the same property, using job's conf object using job.getConfiguration().setClass(*mapred.map.multithreadedrunner.class*, MultithreadedMapper.class, Mapper.class), throws OOM.
