> After caching a graph, its edge and vertex RDDs still return
> StorageLevel.None.
> Reproduce error:
> {code}
> import org.apache.spark.graphx.{Edge, Graph}
> val edges = Seq(
> Edge[Double](0, 1, 0),
> Edge[Double](1, 2, 0),
> Edge[Double](2, 3, 0),
> Edge[Double](3, 4, 0))
> val g = Graph.fromEdges[Double,Double](sc.parallelize(edges), 0)
> g.vertices.getStorageLevel // returns value for StorageLevel.None
> g.edges.getStorageLevel // returns value for StorageLevel.None
> g.cache()
> g.vertices.count()
> g.edges.count()
> g.vertices.getStorageLevel // returns value for StorageLevel.None
> g.edges.getStorageLevel // returns value for StorageLevel.None
> {code}
