> I've had a few requests for Crunch to support existing Mappers and Reducers
> using the underlying Java APIs as part of regular pipelines, so that users
> could evolve existing MapReduce jobs into Crunch pipelines gradually, instead
> of being forced to rewrite everything all at once in order to map it onto
> Crunch's model.
