> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3521
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Robert Joseph Evans

> The hadoop streaming command will ignore any command line arguments to it.
> {code}
> hadoop jar streaming.jar -input input -output output -mapper cat -reducer cat
> ThisIsABadArgument
> {code}
> Works just fine. This can mask issues where quotes were mistakenly missed
> like
> {code}

> -reducer cat -archive someArchive.tgz
> {code}
> Streaming should fail if it encounters an unexpected command line parameter
