> PipeMapper currently does not emit the key when using TextInputFormat. If you 
> switch to input formats (eg LzoTextInputFormat) the key will be emitted. We 
> should add an option so users can explicitly make streaming not emit the key 
> so they can change input formats without breaking or having to modify their 
> existing programs.
