This should be sent to the user mailing list, I think. It depends what you want to do with the RDD, so yes you could throw around (String, HashMap<String,List<String>>) tuples or perhaps you'd like to be able to groupByKey, reduceByKey on the key and sub-key as a composite in which case JavaPairRDD<Tuple2<String,String>, List<String>> might be more appropriate. Not really clear what you are asking.
