Hi Folks, I've spent the last few nights trying to read through as much of the sentry documentation as I can and have a couple of very basic questions particularly surrounding my requirement to have a secure Hadoop ecosystem. Say for example I want to lock down the entire Hadoop cluster including all system ports, WebUI's as well as implementation of security based roles and authorization. Is Sentry the tool to use? Do I also need to have configured and be running Hadoop in secure mode? I appreciate any feedback on this one as it is not immediately obvious looking at the Sentry website and documentation (I don't think) if there are other options over and above Sentry to make the cluster secure. Thanks Lewis
