RangePartitioner

class RangePartitioner[K, V] extends Partitioner

A org.apache.spark.Partitioner that partitions sortable records by range into roughly equal ranges. The ranges are determined by sampling the content of the RDD passed in.

Note that the actual number of partitions created by the RangePartitioner might not be the same as the partitions parameter, in the case where the number of sampled records is less than the value of partitions.
