>
> 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].
