Failure of Vertex reflection for putVertexList from GIRAPH-27 
--------------------------------------------------------------

                 Key: GIRAPH-34
                 URL: https://issues.apache.org/jira/browse/GIRAPH-34
             Project: Giraph
          Issue Type: Bug
            Reporter: Christian Kunz
            Assignee: Avery Ching


Christian actually found this bug.  I am filing the JIRA on his behalf.  Here's my error when
running TestVertexRangeBalancer.  

java.lang.RuntimeException: java.io.IOException: Call to returnwhose-lm/10.72.107.231:30002

I identified and fixed the issue by making BasicVertex implement Configurable and making the
graph state set in BasicRPCCommunications.  There is one more error though that I'll try and
solve before putting up a reviewboard.
