> Since I need to call:
> MultiStageMRConfToTezTranslator.translateVertexConfToTez(vertexConf, predecessorConf);
> for each edge to translate the graph into a dag, it would be really helpful if I could separate creation of the vertex from setting the final payload. That way I don't have to traverse the graph multiple times.
> I believe that payload is only used once submit is called, so this shouldn't be much of a problem.
