Avery Ching updated GIRAPH-34:
------------------------------
Attachment: GIRAPH-34.patch
Try running the unittests against an actual Hadoop instance (i.e. if you run
'mvn package -Dprop.mapred.job.tracker=localhost:50300
-Dtest=TestVertexRangeBalancer'). I have a fix for the first part
(reflection), but it seems like there is another component to the bug where
messages are getting delivered early in some weird cases...
Unfortunately it's a little hard to rip the fix out of my checkout since I was
working on GIRAPH-17. This is a part of it to make the Vertex configurable
since in putVertexList will reflect the Vertex and reflection fails because of
trying to get the context from a null graph state. Sorry for the lack of
detail but I have to wake up in less than 4 hours! =)

> 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.
