Subject How to do nested foreach with RDD
Date Sun, 22 Mar 2015 05:37:48 GMT

I have two big RDD, and I need to do some math against each pair of them.
Traditionally, it is like a nested for-loop. But for RDD, it cause a nested
RDD which is prohibited.

Currently, I am collecting one of them, then do a nested for-loop, so to
avoid nested RDD. But would like to know if there's spark-way to do this.
