Alexander Pivovarov created SPARK-17877:
-------------------------------------------
Summary: Can not checkpoint connectedComponents resulting graph
Key: SPARK-17877
URL: https://issues.apache.org/jira/browse/SPARK-17877
Project: Spark
Issue Type: Bug
Components: GraphX
Affects Versions: 2.0.1, 1.6.2, 1.5.2
Reporter: Alexander Pivovarov
Priority: Minor
The following code demonstrates an issue
{code}
import org.apache.spark.graphx._
val users = sc.parallelize(List((3L, ("lucas", "student")), (7L, ("john",
"postdoc")), (5L, ("matt", "prof")), (2L, ("kelly", "prof"))))
val rel = sc.parallelize(List(Edge(3L, 7L, "collab"), Edge(5L, 3L, "advisor"),
Edge(2L, 5L, "colleague"), Edge(5L, 7L, "pi")))
sc.setCheckpointDir("/tmp/check")
val g = Graph(users, rel)
g.checkpoint
val gg = g.connectedComponents()
gg.checkpoint
gg.vertices.collect
gg.edges.collect
gg.isCheckpointed
// res5: Boolean = false
```
I think the last line should return true instead of false
