[SPARK-5461] [graphx] Add isCheckpointed, getCheckpointedFiles methods to
Graph
Added the 2 methods to Graph and GraphImpl. Both make calls to the
underlying vertex and edge RDDs.
This is needed for another PR (for LDA):
[https://github.com/apache/spark/pull/4047]
Notes:
* getCheckpointedFiles is plural and returns a Seq[String] instead of an
Option[String].
* I attempted to test to make sure the methods returned the correct values
after checkpointing. It did not work; I guess that checkpointing does not
occur quickly enough? I noticed that there are not checkpointing tests for
RDDs; is it just hard to test well?
