Description

In graph computing, when sends message to non-exist vertex, job will fail. The problem triggered from iterate method of org.apache.hama.graph.GraphJobCounter.
Un-completed graph input exists in the real world. Should we ignore these messages sent to non-exist vertext? Or, should we add the mechanism, adds the additional vertex when Vertex.addEdge called?
