Subject [jira] Created: (MAPREDUCE-1977) [Rumen] Do Not Store CDFs in Output JSON Files
Date Wed, 28 Jul 2010 10:02:19 GMT
[Rumen] Do Not Store CDFs in Output JSON Files
----------------------------------------------

                 Key: MAPREDUCE-1977
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1977
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Ranjit Mathew
            Assignee: Amar Kamat


Per-Job Cumulative Distribution Functions (CDFs) stored in JSON files emitted by Rumen are
redundant and waste space (~30%).
They can easily be re-computed upon loading or just-in-time upon request.
