New members: your first post is moderated to prevent spamming to the list. Please be patient! It should switch to unmoderated after the first.

Error reports: Please be sure you've read and applied the steps described in https://github.com/RevolutionAnalytics/RHadoop/wiki/Debugging-rmr-programs. Please post a reproducible test case (including input data) and a real error, not Error: NA. If you only have a Error:NA, please go back to the debugging document and get an informative error message from the logs. One more thing, no screenshots. Text logs can be filtered, compared etc. Screenshots, not so much.
