      Description

      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.
