bq. I think the better fix would be in StreamUtil.goodClassOrNull method, which checks if
the class is specified and when it is not found, logs it at info level and throws an exception.
It should not silently ignore and continue.

> 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.
