Correct Answer:
See the explanation for Step by Step Solution and configuration. Explanation: Solution : c.sortByKey(false).collect sortByKey [Ordered] : This function sorts the input RDD's data and stores it in a new RDD. "The output RDD is a shuffled RDD because it stores data that is output by a reducer which has been shuffled. The implementation of this function is actually very clever. First, it uses a range partitioner to partition the data in ranges within the shuffled RDD. Then it sorts these ranges individually with mapPartitions using standard sort mechanisms.
