Github user ankurdave commented on the pull request: https://github.com/apache/spark/pull/4733#issuecomment-77987006 Oh, sorry for not catching this earlier: diff requires both VertexRDDs to share the same index, so I don't think it'll work to convert the pair RDD into a VertexRDD using `VertexRDD(other)`; you'll need to use `this.aggregateUsingIndex(other, (a, b) => a)`. Also, since this is actually a bit tricky, it would be nice to have a test.
