RDDBarrier

class RDDBarrier[T] extends AnyRef

:: Experimental :: Wraps an RDD in a barrier stage, which forces Spark to launch tasks of this stage together. org.apache.spark.rdd.RDDBarrier instances are created by org.apache.spark.rdd.RDD#barrier.

  13. def mapPartitionsWithEvaluator[U](evaluatorFactory: PartitionEvaluatorFactory[T, U])(implicit arg0: ClassTag[U]): RDD[U]

    Return a new RDD by applying an evaluator to each partition of the wrapped RDD.

    Return a new RDD by applying an evaluator to each partition of the wrapped RDD. The given evaluator factory will be serialized and sent to executors, and each task will create an evaluator with the factory, and use the evaluator to transform the data of the input partition.
