Description

After caching a graph, its edge and vertex RDDs still return StorageLevel.None.

Reproduce error:

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
