Subject [jira] Created: (MAPREDUCE-1042) rumen should be able to output compressed trace files

rumen should be able to output compressed trace files
-----------------------------------------------------

                 Key: MAPREDUCE-1042
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1042
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Dick King
            Assignee: Dick King


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.
