Summary: org.apache.spark.graphx.VertexRDD.diff does not work
Key: SPARK-4600
URL: https://issues.apache.org/jira/browse/SPARK-4600
Project: Spark
Issue Type: Bug
Environment: scala 2.10.4
spark 1.1.0
Reporter: Teppei Tosa
VertexRDD.diff doesn't work.
For example :
val setA: VertexRDD[Int] = VertexRDD(sc.parallelize(0L until 2L).map(id => (id,
id.toInt)))
setA.collect.foreach(println(_))
// (0,0)
// (1,1)
val setB: VertexRDD[Int] = VertexRDD(sc.parallelize(1L until 3L).map(id => (id,
id.toInt)))
setB.collect.foreach(println(_))
// (1,1)
// (2,2)
val diff = setA.diff(setB)
diff.collect.foreach(println(_))
// printed none
