Subject [jira] [Created] (GIRAPH-245) BasicRPCCommunications fails with custom vertices
Date Tue, 10 Jul 2012 12:40:40 GMT
Sebastian Schelter created GIRAPH-245:

             Summary: BasicRPCCommunications fails with custom vertices
                 Key: GIRAPH-245
             Project: Giraph
          Issue Type: Bug
    Affects Versions: 0.2.0
            Reporter: Sebastian Schelter

BasicRPCCommunications assumes that every vertex is an instance of MutableVertex in line 1265:

      if (vertex != null) {
        ((MutableVertex<I, V, E, M>) vertex).setVertexId(vertexIndex);

For custom vertices that only extend BasicVertex, this code fails with a ClassCastException
