> Most of our shuffle methods can take a Partitioner or a number of partitions as a second
argument, but for some reason reduceByKey takes the Partitioner as a *first* argument: http://spark.apache.org/docs/0.9.1/api/core/#org.apache.spark.rdd.PairRDDFunctions.
We should deprecate that version and add one where the Partitioner is the second argument.
