Subject DefaultVertexValueFactory can not access a member of class ...
Date Fri, 21 Jun 2013 11:41:12 GMT
I'm using giraph trunk, and getting the following error:

Caused by: java.lang.IllegalAccessException: Class
org.apache.giraph.graph.DefaultVertexValueFactory can not access a
member of class with modifiers ""
	at sun.reflect.Reflection.ensureMemberAccess(
	at java.lang.Class.newInstance0(
	at java.lang.Class.newInstance(
	at org.apache.giraph.graph.DefaultVertexValueFactory.createVertexValue(

Here, BCNode is our own class which implements Writable. All works
fine until we've reached 'map 100%'. Then it stalls. Is there
something I'm not considering here? The code I use for BCNode is found

The class I execute in giraph is found here:

The command I execute is the following:

hadoop jar giraph.jar org.apache.giraph.GiraphRunner -vif -vip input/input -of -op output -w

Could someone give me some pointers?

ps. all code is accessible here:
