 <p>
 The class you supply for the input format should return key/value pairs of Text class. If
you do not specify an input format class, the TextInputFormat is used as the default. Since
the TextInputFormat returns keys of LongWritable class, which are actually not part of the
input data, the keys will be discarded; only the values will be piped to the streaming mapper.
