6. def distributeToPartitions[B, D](mapping: RDD[(K, D)], partitioner: Partitioner)(f: (A) ⇒ B)(implicit arg0: ClassTag[D]): RDD[(D, (K, B))]

   

   Creates an RDD having each of required objects distributed to all required destinations

   Creates an RDD having each of required objects distributed to all required destinations

   If the data and/or mapping are partitioned with the same partitioner, no shuffle is required.

   mapping

   Mapping of keys to destinations. Duplicate destinations from different partitions are coalesced.

   partitioner

   Partitioner to use. Operation is more efficient if data is partitioned with the same partitioner

   f

   Function to apply to values. It's called exactly once for each value in data

11. def groupWithinPartitionsByKey: RDD[(K, Iterator[A])]

    

    Utility used to group data by key within RDD partitions by a key, assuming that RDD is already partitioned and sorted by key.

    Utility used to group data by key within RDD partitions by a key, assuming that RDD is already partitioned and sorted by key. The RDD data are processed sequentialy without shuffling and materializing them in memory.

    returns

    RDD with key -> values.
