----------------------------------------
Summary: EdgeRDD, VertexRDD getStorageLevel return bad values
Key: SPARK-5534
URL: https://issues.apache.org/jira/browse/SPARK-5534
Project: Spark
Issue Type: Bug
Components: GraphX
Affects Versions: 1.3.0
Reporter: Joseph K. Bradley
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}
