> This is an umbrella JIRA for adding model export/import to the spark.ml API.  This JIRA is for adding the internal Saveable/Loadable API and Parquet-based format, not for other formats like PMML.
> This will require the following steps:
> * Add export/import for all PipelineStages supported by spark.ml
> ** This will include some Transformers which are not Models.
> ** These can use almost the same format as the spark.mllib model save/load functions, but the model metadata must store a different class name (marking the class as a spark.ml class).
> * After all PipelineStages support save/load, add an interface which forces future additions to support save/load.
