> Currently when saving a DataFrame in Spark it is persisted as upserts. Having 
> an option to do saves natively via HFiles, as the MapReduce loader does, 
> would be a great performance improvement for large bulk loads. The current 
> work around to reduce the load on the regionservers would be to save to csv 
> from Spark then load via the MapReduce loader.
