How to import mllib.rdd.RDDFunctions into the spark-shell

[Stephen Boesch]

I seem to recall there were some specific requirements on how to import the
implicits.

Here is the issue:

scala> import org.apache.spark.mllib.rdd.RDDFunctions._
<console>:10: error: object RDDFunctions in package rdd cannot be accessed
in package org.apache.spark.mllib.rdd
       import org.apache.spark.mllib.rdd.RDDFunctions._
