@dwmclary Thank you for working on it. I think we need to handle complex
types. The approach @NathanHowell is using looks good since we do not need to
convert Scala collections to Java collections to generate the JSON string.
Regarding the Python API, `toJSON` will returns a Scala RDD and I think you
can use `jrdd = self._jvm.JavaRDD.fromRDD` to generate a Java RDD and then
[create an RDD at the Python
side](https://github.com/apache/spark/blob/master/python/pyspark/rdd.py#L123)
(`RDD(jrdd, self._sc, self._jrdd_deserializer)`). @davies is it the right way?
