I'm not sure if this patch actually works. The following code works with
RDD, but the similar code (below) does not work with Graph:
```
// For RDD:
val rdd = sc.parallelize(Seq(1,2,3))
sc.setCheckpointDir("tmpcheckpoints")
rdd.checkpoint()
rdd.count
rdd.isCheckpointed // returns true
```
```
// For Graph
import org.apache.spark.graphx.Graph
import org.apache.spark.graphx.Edge
sc.setCheckpointDir("tmpcheckpoints")
val edges = sc.parallelize(Seq(Edge[Int](0,1), Edge[Int](1,2),
Edge[Int](2,3)))
val g = Graph.fromEdges(edges, 0)
g.checkpoint()
g.vertices.count
g.edges.count
g.isCheckpointed // returns false
g.vertices.isCheckpointed // returns false
g.edges.isCheckpointed // returns false
```
