[jira] [Resolved] (GIRAPH-34) Failure of Vertex reflection for
putVertexList from GIRAPH-27
[ https://issues.apache.org/jira/browse/GIRAPH-34?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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()?

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

> 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.
