Hi, I want to explore R for Hadoop. Where can I get the download ? Any suggested material on the website to explore ? Please advise.

I faced a similar exception with Rhipe-0.68 in CDH4. The reason was because that version of Rhipe doesnt support CDH4. My problem got resolved with the release of Rhipe-0.73. So check whether it supports your hadoop version.
