abstract class Partitioner extends Serializable

An object that defines how the elements in a key-value pair RDD are partitioned by key. Maps each key to a partition ID, from 0 to numPartitions - 1.

Note that, partitioner must be deterministic, i.e. it must return the same partition id given the same partition key.
