Robert Joseph Evans commented on MAPREDUCE-3521:
------------------------------------------------
The failures are expected because I changed tools, which test-patch is not set
up to deal with yet HADOOP-7725.
I ran the streaming tests manually and they all pass.

> Project: Hadoop Map/Reduce

> 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}
> hadoop jar streaming.jar -input input -output output -mapper xargs cat
> -reducer cat -archive someArchive.tgz
> {code}
> Streaming should fail if it encounters an unexpected command line parameter
