Checkout slides #19 & #5, Hue is getting everywhere and is compatible with Hadoop 0.20 / 1.2.0 / 2.2.0: http://gethue.com/hue-goes-to-paris-hug-france/
Hue has tarball releases releases that you are free to install. You can also simply clone the source code (Hue is open source and Apache Licenced) github: https://github.com/cloudera/hue and build the branch you want.
Upstream documentation is here or CDH's one here.
Hue is also packaged in BigTop (and so based on Vanilla Hadoop).
Hue is a Web Server (Django based) which acts as a view on top of Hadoop. So Hue just needs to be installed and then configured by adding the hosts of NameNode, JobTracker, Resource Manager, Oozie, HiveServer... etc in its hue.ini.
Also, as detailed on the gehue.com/releases, the version you need might depend on your Hive version.
Notice that without Cloudera's distribution your mileage might vary but feel free to chime-in on the Hue user-list or gethue.com ;)
We are also seeing for improving Hue setup with Amazon AWS/EMR!
