Hi Harsha,    Thanks for the explanation. In extension to the topic, I need small clarification - we recently implemented sentry on impala, based on below KB [1] article, we can't execute "Invalidate all metadata and rebuild index" and "Perform incremental metadata update" , since we don't have access to all the DB's, it's fair as well. Now my question is - 1. I am not able to see new DB in Hue impala, I can see the same from beeline or impala shell. How to fix or solve this ? 2. I can execute invalidate metadata on table from impala shell but I have 50+ DB's and 10's of tables in each db. Is there any option to run invalidate metadata ion DB level instead of individual table?
