Klaas, could you please shed some light on how you are thinking of implementing this? I guess
all what you are saying happens in the framework's PipeMapper, is that right?

> Since HADOOP-4842 got committed, Streaming allows both commands and Java classes to be
specified as mapper, reducer, and combiner, but the {{-partitioner}} option is still limited
to Java classes only. Allowing commands to be specified as partitioner as well would greatly
improve the flexibility of Streaming programs.
