Description: 
The return type for SparkContext.emptyRDD is EmptyRDD[T].

It should be RDD[T].  That means you have to add extra type annotations on code 
like the below (which creates a union of RDDs over some subset of paths in a 
folder)

{code}
val rdds = Seq("a", "b", "c").foldLeft[RDD[String]](sc.emptyRDD[String]) { 
(rdd, path) ⇒
  rdd.union(sc.textFile(path))
}
{code}

  was:
