> Right now MapRedTask does an exec on the hadoop command line. This prevents us from stepping
through query execution code. If there were an option to run hadoop via MiniMR, this will
create tasks within the same VM and so allows stepping into the execution code. See, src/test/org/apache/hadoop/mapred/
in the hadoop source code for an example.
