               Status: Patch Available  (was: Open)

This patch implements Rumen as described by this issue.  Rumen consumes job tracker log directories
and produces the job traces that mumakil and GridMMIX cosume.

>  We propose a new map/reduce component, rumen, which can be used to process job history
logs to produce any or all of the following:
>       * Retrospective info describing the statistical behavior of the
> amount of time it would have taken to launch a job into a certain
> percentage of the number of mapper slots in the log's cluster, given the
> load over the period covered by the log
>       * Statistical info as to the runtimes and shuffle times, etc. of
> the tasks and jobs covered by the log
>       * files describing detailed job trace information, and the
> network topology as inferred from the host locations and rack IDs that
> arise in the job tracker log.  In addition to this facility, rumen
> includes readers for this information to return job and detailed task
> information to other tools.
>         These other tools include a more advanced version of gridmix, and also includes
mumak: see blocked issues.
