I would like to start a Map-Reduce job that does not read data from an input file or from
a database.  I would like to pass 3 arguments to the Mapper & Reducer to work on.  Basically,
these arguments are keys on the 3 different tables on HBase.

In other words, I don't want to use FileInputFormat or DbInputFormat because everything I
need is already on HBase. 

How can I do this?  Please let me know.  Thanks.
