Can i install HUE and Beeswax apps in my open source apache hadoop installation ? OR is it only for Cloudera ?
Also if i use CDH4 will it suit good for production environment (cdh opensource) ?
Hue is compatible with Hapache Hadoop 1.2.0 and later and is in the main distributions.
Hive might depend on the Hue version (cf. documentation http://gethue.tumblr.com/tagged/release).
CDH4 is used by thousands of organizations and is definitely good for production.
Yes, as said above, any Hadoop > 1.2.0.
Hue is included into Apache BigTop (which ships Apache Hadoop) and in the main other distribution (of course, your mileage might vary).
