Description

It should pass the ascending parameter on. Instead, it always passes "true".

  /**
   * Sort the RDD by key, so that each partition contains a sorted range of the elements. Calling
   * `collect` or `save` on the resulting RDD will return or output an ordered list of records
   * (in the `save` case, they will be written to multiple `part-X` files in the filesystem, in
   * order of the keys).
   */
  def sortByKey(ascending: Boolean): JavaPairRDD[K, V] = {
    val comp = com.google.common.collect.Ordering.natural().asInstanceOf[Comparator[K]]
    sortByKey(comp, true)
  }
