Hi All,
I have build Giraph for patch-854 on hadoop1.0.0. I have run the example of
SimpleShortestPathsComputation successfully but when I try to run the some
other code by following the same architecture as used in
SimpleShortestPathsComputation Example, it gives me following error-
Exception in thread "main" java.lang.RuntimeException: class MyVertexClass

and when I implement the Vertex Interface, it gives me following exception-
