----------------------------------------
Description:
Looks like Graph does not clean all RDDs from the cache on unpersist
{code}
// open spark-shell 1.5.2
// run
import org.apache.spark.graphx._
val vert = sc.parallelize(List((1L, 1), (2L, 2), (3L, 3)), 1)
val edges = sc.parallelize(List(Edge[Long](1L, 2L), Edge[Long](1L, 3L)), 1)
val g0 = Graph(vert, edges)
val g = g0.partitionBy(PartitionStrategy.EdgePartition2D, 2)
val cc = g.connectedComponents()
cc.unpersist()
g.unpersist()
g0.unpersist()
vert.unpersist()
edges.unpersist()
{code}
