Joseph K. Bradley commented on SPARK-5461:
------------------------------------------
[~ankurdave] Do you have thoughts about this issue? It's a bit tricky (for
me). I want to call isCheckpionted for a Graph.
For that, I overrode isCheckpointed for VertexRDDImpl and EdgeRDDImpl, where
they call partitionsRDD.isCheckpointed. However, partitionsRDD is transient,
so it fails when isCheckpointed is called on workers. Do you have suggestions
for a solution? E.g., make partitionsRDD non-transient, implement
Vertex/EdgeRDDImpl.isCheckpointed by checking something other than
partitionsRDD, etc. Thanks very much!
> Graph should have isCheckpointed, getCheckpointFiles methods

> Project: Spark
> Issue Type: Improvement
> Components: GraphX
> Affects Versions: 1.3.0
> Reporter: Joseph K. Bradley
> Assignee: Joseph K. Bradley
> Priority: Minor
>
> Graph has a checkpoint method but does not have other helper functionality
> which RDD has. Proposal:
> {code}
> /**
> * Return whether this Graph has been checkpointed or not
> */
> def isCheckpointed: Boolean
> /**
> * Gets the name of the files to which this Graph was checkpointed
> */
> def getCheckpointFiles: Seq[String]
> {code}
> I need this for [SPARK-1405].
