Are people working on this currently? I'd be happy to help out perhaps if not.

> Currently, the Spark runner translates batch pipelines into RDD code, meaning it doesn't benefit from the optimizations DataFrames (which isn't type-safe) enjoys.
> With Datasets, batch pipelines will benefit the optimizations, adding to that that Datasets are type-safe and encoder-based they seem like a much better fit for the Beam model.
> Looking ahead, Datasets is a good choice since it's the basis for the future of Spark streaming as well  (Structured Streaming) so this will hopefully lay a solid foundation for a native integration between Spark 2.0 and Beam.
