Michael Malak created SPARK-1817: ------------------------------------ Summary: 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 Affects Versions: 0.9.0 Reporter: Michael Malak
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 divide the total number of elements in the RDD.
