---------------------------------
Priority: Major (was: Minor)
> RDD zip erroneous when partitions do not divide RDD count
> ---------------------------------------------------------

> Key: SPARK-1817
> URL: https://issues.apache.org/jira/browse/SPARK-1817
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 0.9.0, 1.0.0
> Reporter: Michael Malak
> Assignee: Kan Zhang

> Example:
> scala> sc.parallelize(1L to 2L,4).zip(sc.parallelize(11 to 12,4)).collect
> res1: Array[(Long, Int)] = Array((2,11))
> But more generally, it's whenever the number of partitions does not evenly
