Dick King updated MAPREDUCE-1295: --------------------------------- Attachment: mapreduce-1297--2009-12-14.patch > We need a job trace manipulator to build gridmix runs. > ------------------------------------------------------ > > Key: MAPREDUCE-1295 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1295 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Reporter: Dick King > Assignee: Dick King > Attachments: mapreduce-1297--2009-12-14.patch > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
