> There are two orthogonal questions to answer when processing a job tracker log: how will
the logs and the xml configuration files be packaged, and in which release of hadoop map/reduce
were the logs generated?  The existing rumen only has a couple of answers to this question.
 The new engine will handle three answers to the version question: 0.18, 0.20 and current,
and two answers to the packaging question: separate files with names derived from the job
ID, and concatenated files with a header between sections [used for easier file interchange].
