Key: HADOOP-2906
URL: https://issues.apache.org/jira/browse/HADOOP-2906
Project: Hadoop Core
Issue Type: New Feature
Components: mapred
Reporter: Runping Qi
Assignee: Runping Qi
Attachments: patch.2096.6.txt


I've a few apps that require to write out data into different files/directories depending on keys and/or configuration variables.
I've implemented such classes for those apps. I noticed that many other users have similar need from time to time.
So I think it may be a good idea to contribute to Hadoop mapred.lib package so that other users can benefit from it.
