             Summary: In PageRankBenchmark, remove unused handling of -t 2
                 Key: GIRAPH-502
                 URL: https://issues.apache.org/jira/browse/GIRAPH-502
             Project: Giraph
          Issue Type: Improvement
            Reporter: Eugene Koontz
            Assignee: Eugene Koontz
            Priority: Minor


PagerankBenchmark accepts, among other options, -t. For the usage message, it's treated as:

t=0 (no combiner)
t=1 (DoubleSumCombiner (default))

However the code mentions a t=2, but this ends up being treated the same as t=0:

{code}
if (!cmd.hasOption('t') ||
  (Integer.parseInt(cmd.getOptionValue('t')) == 2)) {
     configuration.setVertexCombinerClass(
          DoubleSumCombiner.class);
    } else if (Integer.parseInt(cmd.getOptionValue('t')) == 1) {
     configuration.setVertexCombinerClass(
          DoubleSumCombiner.class);
    }
{code}

We should make the code usage conform to the usage message and remove the extraneous -t=2 handling.
