> Rumen: a tool to extract job characterization data from job tracker logs
> ------------------------------------------------------------------------
>
> Key: MAPREDUCE-751
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-751
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 0.20.1, 0.21.0
> Reporter: Dick King
> Fix For: 0.20.1, 0.21.0
>
> Attachments: 2009-08-19--1030.patch, mapreduce-751--2009-07-23.patch
>
>
> 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.
