Not at all. The daemon part of Hadoop UI is running under a configurable user and will issue calls to Hadoop on behalf of this user. Its not much different from the standard web UI in this domain. The plan is to introduce a authentication layer with one of the next releases. It will be based on Spring Security and thus enables you to use many different authentication providers. So downloading all those Spring libraries along with the project will finally pay off ;) > I'd love nothing more to be able to give my users a dead-simple way to move > files on and off the cluster.

Gah, I sound like my boss. Theres nothing arcane about Flex, but please don't tell anybody. You can get the recently open sourced (MPL) SDK for any platform supporting Java and compile Hadoop UI using ant. Other libraries used are flexlib (MIT license), Spring (Apache L.), BlazeDS (LGPL). In case I would have to look for a new job, as you suggest, other people would be able to fork as long as they know some Action Script, the actual language used in Flex, and some XML. - Stefan
