 Sum on empty RDD fails with exception
 -

 Key: SPARK-6878
 URL: https://issues.apache.org/jira/browse/SPARK-6878
 Project: Spark
  Issue Type: Bug
  Components: Spark Core
Affects Versions: 1.2.0
Reporter: Erik van Oosten
Assignee: Erik van Oosten
Priority: Minor
 Fix For: 1.2.2, 1.3.2, 1.4.0


 {{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}
