> Right now, unioning a PTable<K, V> and a PCollection<Pair<K, V>> in crunch-spark will fail due to a ClassCastException-- one parent PCollection will return a JavaRDD, while the other will return a JavaPairRDD, and we'll only be expecting one type to be returned. This unioning works correctly in the MR impl, so we should add a fix for it to work correctly in crunch-spark as well.
