                 Key: SPARK-15717
                 URL: https://issues.apache.org/jira/browse/SPARK-15717

          Issue Type: Bug
          Components: GraphX

            Reporter: Anderson de Andrade


A checkpointed (materialized) VertexRDD throws the following exception when 
collected:

java.lang.ArrayStoreException:

Can be duplicated by running:
{code:scala}
graph.vertices.checkpoint()
graph.vertices.count() // materialize
graph.vertices.collect()
{code:xml}
