      Description

      If the value of 'spark.default.parallelism' does not match the number of partitoins in EdgePartition(EdgeRDDImpl),
      the following error occurs in ReplicatedVertexView.scala:72;

      object GraphTest extends Logging {
      def run[VD: ClassTag, ED: ClassTag](graph: Graph[VD, ED]): VertexRDD[Int] = {
      graph.aggregateMessages[Int](
      ctx => {
      ctx.sendToSrc(1)
      ctx.sendToDst(2)
      },
      _ + _)
      }
      }

      val g = GraphLoader.edgeListFile(sc, "graph.txt")
      val rdd = GraphTest.run(g)
