Hi Jay, Probably makes sense to move this to the cdh-user list if you have any Cloudera-specific questions. But I just wanted to clarify: CDH doesn't make any API changes that aren't already upstream. So, in some places, CDH may be ahead of whatever Apache release you are comparing against, but it is always made up of patches from the Apache trunk. In the specific case of MultipleInputs, we did backport the new API implementation from Apache Hadoop 0.21+.
If you find something in CDH that you would like backported to upstream Apache Hadoop 1.0.x, please feel free to file a JIRA and assign it to me - I'm happy to look into it for you.
