> 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.
