[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.
