(was: How can we mark classes so the testing infrastructure can identify them. Should the
classes be name TestMR?)

> 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/TestMiniMRWithDFS.java
in the hadoop source code for an example.
