It looks like all of that is building up to spark 2.0 (for random forests /
gbts / etc.). Ah well...thanks for your help. Was interesting digging into the
depths.

There are still some issues, around feature names, etc. Trying to pin them down.

I was hoping for a more automated way of
getting the map. Since the trained model already knows about the value, perhaps
it's possible to grab it for storage?
Thanks,Ashic.

There are methods for converting the dataframe based random forest models
to the old RDD based models and vice versa. Perhaps using these will help
given that the old models can be saved and loaded?
In order to use them however you will need to write code in the
org.apache.spark.ml package.
