Harsh J commented on MAPREDUCE-199: ----------------------------------- Thanks for the feedback Ted, I'll come up with another patch that does it in the same way as the InputSplit structures as soon as I get some more free cycles. > Locality hints for Reduce > ------------------------- > > Key: MAPREDUCE-199 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-199 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Components: applicationmaster, mrv2 > Reporter: Benjamin Reed > Assignee: Harsh J > Attachments: MAPREDUCE-199.patch, MAPREDUCE-199.patch > > > It would be nice if we could add method to OutputFormat that would allow a > job to indicate where a reducer for a given partition should should run. This > is similar to the getSplits() method on InputFormat. In our application the > reducer is using other data in addition to the map outputs during processing > and data accesses could be made more efficient if the JobTracker scheduled > the reducers to run on specific hosts. -- This message is automatically generated by JIRA.
