• Grant Hive table access in Ranger

2. Enable HDFS location access for the user

Login to Ranger and select HDFS Policy

Validate the HDFS location access is restricted to ensure Ranger policy is working as expected

Add a new policy if not exists

Grant table access to required users and validate the access by querying the table

Before applying Row Level Filter

Same query triggered after applying the filter and only “state = ca” records are displayed to user Alice
