------------------------------------------
Hi Arun,
Yes, these were present in the testcases but never used by the actual streaming
command in those test cases. The invalid option passed on were ignored by the
previous streaming code. The patch now catches such invalid options, so I
updated the depending test cases as well.
> Streaming does not handle invalid -inputformat (typo by users for example)

> Hadoop Streaming does not handle invalid inputformat class. For example
> -inputformat INVALID class would not be thrown as an error. Instead it
> defaults to StreamInputFormat. If an invalid inputformat is specified, it is
> good to fail.
