Okay here are the two options.
1. createRDD returns RDD[(K,V)] or RDD[R], and DStream.foreachRDD uses
rdd.asInstanceOf[HasOffsetRanges]
2. createRDD returns KafkaRDD[(K,V)] or KafkaRDD[R] and DStream.foreachRDD
uses rdd.asInstanceOf[KafkaRDD[_]]
I think I am okay with either one. Stepping back, my original concern was
returning something that had no binary compatibility issues. Both solution
suffices. Between these two, since you feel so strongly against (2), lets go
with (1).
