Return RDD of largest N values from another RDD in SPARK

Question

I\'m trying to filter an RDD of tuples to return the largest N tuples based on key values. I need the return format to be an RDD.

So the RDD:

[(4, \'         


        

Answer 1

A less effort approach since you only want to convert take(N) results to new RDD.

sc.parallelize(yourSortedRdd.take(Nth))
