> 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)
