HI Jing, Am answering this over the CDH-users list, since your question is CDH-specific. You may view/subscribe to it at http://groups.google.com/a/cloudera.org/forum/?fromgroups#!forum/cdh-user ([email protected]).

We have stability and feature patches from trunk on top, as is listed on the release notes. See also: http://www.cloudera.com/hadoop-details/. For stable MR execution, aside of the rewritten YARN framework (which is pretty new and not yet recommended for production), we also provide MR1 with CDH4 (Apache Hadoop 2.0.0) which you can run via the MR1 packages. This is sorta the same MR package that is present in the CDH3 releases today. > Are there limitations on cdh packages? CDH too is Apache (ASL) licensed, same as Apache Hadoop, and there are no restrictions on its use aside of what the license requires. -- Harsh J
