PySpark RDDs are (on the Java side) are essentially RDD of pickled objects and mostly (but not entirely) opaque to the JVM. It is possible (by using some internals) to pass a PySpark DataFrame to a Scala library (you may or may not find the talk I gave at Spark Summit useful https://www.youtube.com/watch?v=V6DkTVvy9vk as well as some of the Python examples in https://github.com/high-performance-spark/high-performance-spark-examples ). Good luck! :)
