Avery Ching resolved GIRAPH-34.
-------------------------------
Resolution: Fixed
I've committed with +1's from Dmitriy and Jake. We can think about a better
way to be safe in a future JIRA. Although Jake, how much more expensive it is
to serialize/deserialize to/from a byte[] vs instantiating the object and using
Hadoop's ReflectionUtils.copy()?

> 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.
