> The Pipelines API (spark.ml package) now includes abstractions for single-label prediction: Predictor, Classifier, Regressor.  These assume models are local, where single-Row prediction methods can be used as UDFs.  We need to think about how to support distributed models in these abstractions.
> Should the abstractions be modified somehow?  Or should there be parallel (or inheriting) abstractions, or a mix-in?
> Motivation: We may start supporting distributed models since linear models,  random forests, and other models can get large enough to merit distributed storage and computation.
