> Project: Hadoop Map/Reduce
> Issue Type: New Feature
> Reporter: Dick King

> Rumen produces "job traces", which are JSON format files describing important
> aspects of all jobs that are run [successfully or not] on a hadoop map/reduce
> cluster. There are two packages under development that will consume these
> trace files and produce actions in that cluster or another cluster: gridmix3
> [see jira MAPREDUCE-1124 ] and Mumak [a simulator -- see MAPREDUCE-728 ].
> It would be useful to be able to do two things with job traces, so we can run
> experiments using these two tools: change the duration, and change the
> density. I would like to provide a "folder", a tool that can wrap a
> long-duration execution trace to redistribute its jobs over a shorter
> interval, and also change the density by duplicating or culling away jobs
> from the folded combined job trace.
