> MR jobs sometimes want to just output lines of text, not key/value pairs.
> TextOutputFormat handles this by, if a null value is given, outputting only
> the key with no separator. Streaming jobs are unable to take advantage of
> this, because they can't output null values. A text output format reader
> takes each line as a key and outputs NullWritables for values would allow
> streaming jobs to output lines of text.
