> {{Sum}} on an empty RDD throws an exception. Expected result is {{0}}.
> A simple fix is the replace
> {noformat}
> class DoubleRDDFunctions {
>   def sum(): Double = self.reduce(_ + _)
> {noformat} 
> with:
> {noformat}
> class DoubleRDDFunctions {
>   def sum(): Double = self.aggregate(0.0)(_ + _, _ + _)
> {noformat}
