Re: How to modify collection inside a spark rdd foreach

[Robineast <Ro...@xense.co.uk>]

It's not that clear what you are trying to achieve - what type is myRDD and
where do k and v come from?

Anyway it seems you want to end up with a map or a dictionary which is what
PairRDD is for e.g.

val rdd = sc.makeRDD(Array("1","2","3"))
val pairRDD = rdd.map(el => (el.toInt, el))
