distinct(numPartitions=None) Return a new RDD containing the distinct elements in this RDD. >>> sorted(sc.parallelize([1, 1, 2, 3]).distinct().collect 阅读全文
摘要:
lookup(key) Return the list of values in the RDD for key key. This operation is done efficiently if the RDD has a known partitioner by only searching 阅读全文
