Description

Here are some of the findings by Karam while verifying -info option in streaming:

1. We need to add "Optional" for -mapper, -reducer,-combiner and -file options.
2. For -inputformat and -outputformat options, we should put "Optional" in the prefix for the sake on uniformity.
3. We need to remove -cluster decription.
4. -help option is not displayed in usage message.
5. when displaying message for -info or -help options, we should not display "Streaming Job Failed!"; also exit code should be 0 in case of -help/-info option.
