                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5635

Here is what the TextInputFormat javadoc says:
[TextInputFormat|http://hadoop.apache.org/docs/current/api/org/apache/hadoop/mapreduce/lib/input/TextInputFormat.html]

An InputFormat for plain text files. Files are broken into lines. Either linefeed or carriage-return are used to signal end of line. Keys are the position in the file, and values are the line of text..

FileInputFormat should say the same on
[FileInputFormat|http://hadoop.apache.org/docs/current/api/org/apache/hadoop/mapreduce/lib/input/FileInputFormat.html]
