> Such a StringInputFormat would be like TextInputFormat but with input types of Long and
String, rather than LongWritable and Text. This would allow users to write MapReduce programs
that used only Java native types (i.e. no Writables).
> This is currently not possible to write without changes to Hadoop due to a limitation
in the RecordReader interface explained here: https://issues.apache.org/jira/browse/HADOOP-3413?focusedCommentId=12597935#action_12597935
