Answer 1

It depends on what the format of the TXT file is. Is it one line per record? If so, you can simply use TextInputFormat which creates one record for each line. In your mapper you can parse that line and use it whichever way you choose.

If it isn't one line per record, you might need to write your own InputFormat implementation. Take a look at this tutorial for more info.
