Looking further it appears the functionality I am seeking is in the
following *private[spark] * class ForEachdStream
(version 0.8.1 , yes we are presently using an older release..)
private[streaming]
class ForEachDStream[T: ClassManifest] (
parent: DStream[T],
* foreachFunc: (RDD[T], Time) => Unit*
) extends DStream[Unit](parent.ssc) {
I would like to have access to this structure - particularly the ability to
define an "foreachFunc" that gets applied to each RDD within the DStream.
Is there a means to do so?
