[jira] [Updated] (GIRAPH-502) In PageRankBenchmark, remove unneeded
handling of -t 2
[ https://issues.apache.org/jira/browse/GIRAPH-502?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eugene Koontz updated GIRAPH-502:
---------------------------------
Summary: In PageRankBenchmark, remove unneeded handling of -t 2 (was: In PageRankBenchmark, remove unused handling of -t 2)
> In PageRankBenchmark, remove unneeded 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.
