Sentry is a fine-grained role-based authorization system for Hive among others. We're planning to have a Sentry meetup in NYC coinciding with Hadoop World and Strata 2013. Please RSVP here<http://www.meetup.com/Sentry-User-Meetup/events/138189232/>if you wish to attend the meetup and hear more about how Sentry can help secure your Hive deployment.
Thanks. Shreepadma
