Running foreach on a list of rdds in parallel

[Brandon White]

Hello,

I have a list of rdds

List(rdd1, rdd2, rdd3,rdd4)

I would like to save these rdds in parallel. Right now, it is running each
operation sequentially. I tried using a rdd of rdd but that does not work.

list.foreach { rdd =>
  rdd.saveAsTextFile("/tmp/cache/")
}

Any ideas?
