Subject Exception when replacing EdgeListVertex VertexValue with my own class
Date Wed, 25 Jul 2012 06:27:39 GMT

I have been investigating the exception below. It happens when I
attempt to replace the vertex value class, which had been
LongWritable, with a new class I am writing, MyGraphVertexValue.

I am using Giraph-0.1. I have declared MyGraphVertex public so I am
not sure why this would be happening.



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