> Between Hadoop 1 and 2, the string value of the Configuration option that
> stores the mapper classname in MultithreadedMapper changed from
> "mapred.map.multithreadedrunner.class" to
> "mapreduce.mapper.multithreadedmapper.mapclass".
> Since there is a stable API (getMapperClass()) that abstracts these
> differences away, we should use that instead.
