Hey Rita, All software developed by Cloudera for CDH is Apache (v2) licensed and freely available. See these docs [1,2] for more info.
We publish source packages (which includes the packaging source) and source tarballs, you can find these at http://archive.cloudera.com/cdh/3/. See the CHANGES.txt file (or the cloudera directory in the tarballs) for the specific patches that have been applied. CDH contains a number of projects (Hadoop, Pig, Hive, HBase, Oozie, Flume, Sqoop, Whirr, Hue, ZooKeeper, etc). Most have a small handful of patches applied (often there's only a couple additional patches as we've rolled an upstream dot release that folded in the delta from the previous release). The vast majority of the patches to Hadoop come from the Apache security and append [3, 4] branches. Aside from those the rest are critical backports and bug fixes. In general, we develop upstream first. Hope this clarifies things.
