First time posting so be gentle.
I have recently been working on Ambari Hue Service for HDP 2.x and 3.x. I have finished the repo to install the service for Hue 3.x and 4.x with minimal manual steps. I am now working on a Management Pack that will allow install of HUE to HDP 2 or 3. There is still much work to do, but install and startup is operational with additional steps to configure and setup plugins (hive, hdfs, etc) completed from within ambari.
Master Repo 3.x:
Hue 4.x is in the branch Hue.4.6.0:
I should have the 4.x management pack done soon and will post again when I get it ready. It will be some additional time after that for a full management pack that allows Hue 3 or 4 in any HDP stack from 2.0 to 3.4.
