[SPARK-2514] [mllib] Random RDD generator
Utilities for generating random RDDs.
RandomRDD and RandomVectorRDD are created instead of using
`sc.parallelize(range:Range)` because `Range` objects in Scala can only have
`size <= Int.MaxValue`.
The object `RandomRDDGenerators` can be transformed into a generator class
to reduce the number of auxiliary methods for optional arguments.
You can merge this pull request into a Git repository by running:
$ git pull https://github.com/dorx/spark randomRDD
Alternatively you can review and apply these changes as the patch at:
