Reynold Xin commented on SPARK-5288:
------------------------------------

Maybe we can just expose the leaf types, and hide all the internal ones?

> Several issues we need to address before release 1.3
> * Do we want to make all classes in org.apache.spark.sql.types.dataTypes.scala public? Seems we do not need to make those abstract classes public.
> * Seems NativeType is not a very clear and useful concept. Should we just remove it?
> * We need to Stabilize the type hierarchy of our data types. Seems StringType and Decimal Type should not be primitive types.
