> Key: MAPREDUCE-1042
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1042
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: tools/rumen
> Reporter: Dick King
> Assignee: Dick King
> Fix For: 0.22.0
>
>
> rumen is used primarily to create job trace files which are then processed by other tools.
> These trace files can exceed 100 gigabytes. However, gzip compression normally achieves 15:1 compression on these traces.
> I would like to modify rumen so it can output compressed files directly, rather than outputting unwieldy uncompressed files and letting me compress it later.
