> In the new API, and using MultipleOutputs it is possible to segment output 
> into directories by using MultipleOutputs.write(KEYOUT key, VALUEOUT value, 
> String baseOutputPath) in the Reducer to determine the output directory, and 
> by using LazyOutputFormat at the job-level config to suppress normal output 
> [eg use LazyOutputFormat.setOutputFormatClass(job, TextOutputFormat.class); 
> instead of job.setOutputFormatClass(TextOutputFormat.class);]
> This recreates the functionality previously provided in the old API by using 
> MultipleTextOutputFormat (etc)
