Hi,
Thanks Nanzhu.I tried to implement your suggestion on following scenario.I

elements each.Their is loss of order of elements in partition.Elemest are
partitioned randomly.I need to preserve the order such that the first
I think you should sort each RDD

Hi, I have large data set of numbers ie RDD and wanted to perform a
I didn’t group the integers, but process them in group of two,
partition that
scala val a = sc.parallelize(List(1, 2, 3, 4), 2)
a: org.apache.spark.rdd.RDD[Int] = ParallelCollectionRDD[0] at parallelize at

process each partition and process elements in the partition in group
