Hello everyone, I'm looking for a way to generate unique id's (of type Long) for the addVertexRequest. For example, a very silly implementation that works for graphs with less than 100 vertices would look like this:
public void compute(Iterable<NullWritable> messages) { ... long generatedId = generateId(long getId().get()); addVertexRequest(new LongWritable(generatedId), new DoubleWritable(0)); ... } private long generateId(long seed) { return seed + 100; } But as I said, this is just silly. How can I modify the generateId so that I know the vertex id is unique regardless of the graph size? Panagiotis Eustratiadis.
