@vsreddy   For object based security you have to implement Sentry   1. Install Kerberos (Pre-request: for Sentry) 2. Enabling Kerberos Authentication for Hadoop (Pre-request: Kerberos Installation is different from enable Kerberos to Hadoop) http://www.cloudera.com/documentation/enterprise/latest/topics/cm_sg_intro_kerb.html 3. Add Sentry Service in cluster 4. Enable Sentry service for Hive & Impala. http://www.cloudera.com/documentation/enterprise/latest/topics/cm_sg_sentry_service.html 5. Create necessary groups, users in OS and match the same with Hue. You can try this manually for few users/group for testing purpose...
