Yes it is, but CDH4 is not alpha software. 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.

CDH too is Apache (ASL) licensed, same as Apache Hadoop, and there are
no restrictions on its use aside of what the license requires.
