[jira] Commented: (HADOOP-4304) Add Dumbo to contrib

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-4304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12635505#action_12635505 ] 

Doug Cutting commented on HADOOP-4304:
--------------------------------------

This would make a good addition to Hadoop.

Can you please:
 - provide this as a patch file, attached directly to this issue.
 - import src/contrib/build-contrib.xml rather than replicate it
 - use src/contrib/dumbo/src/{java,python} as the source code paths

Thanks!

> Originally, Dumbo was a simple Python module developed at Last.fm to make writing and running Hadoop Streaming programs very easy, but now it also consists of some (up till now unreleased) helper code in Java (although it can still be used without the Java code). We propose to add Dumbo to "src/contrib" such that the Java classes get build/installed together with the rest of Hadoop, and the Python module can be installed separately at will. A tar.gz of the directory that would have to be added to "src/contrib" is available at
> http://static.last.fm/dumbo/dumbo-contrib.tar.gz
> and more info about Dumbo can be found here:
> * Basic documentation: http://github.com/klbostee/dumbo/wikis
> * Presentation at HUG (where it was first suggested to add Dumbo to contrib): http://skillsmatter.com/podcast/home/dumbo-hadoop-streaming-made-elegant-and-easy
> * Initial announcement: http://blog.last.fm/2008/05/29/python-hadoop-flying-circus-elephant
> For some of the more advanced features of Dumbo (in particular the ones for which the Java classes are needed) there is no public documentation yet, but we could easily fill that gap by moving some of the internal Last.fm documentation to the Hadoop wiki.
