> Shuffle#MergeManager only accepts org.apache.hadoop.mapred.Reducer currently. 
> Because of this, Reduce-side Combiner is not used when using the new API, and 
> just ignored. By supporting it and using the feature from ReduceTask, 
> Reduce-side combiner can be enabled with new API. Please see MAPREDUCE-5221 
> for more detail.
