holdenk commented on SPARK-12040:
---------------------------------
So this came out of wanting to have a matching API between Scala/Python since
the toJson/fromJson methods are public.
We could use the wrappers for any of the models which are implemented in Scala
- but if we do any models/transformers in Python copying the vector to/from the
JVM to write to JSON would be a waste.
