             Summary: Row based Filters added via Hive Ranger policies are not 
pushed to druid
                 Key: HIVE-19941
                 URL: https://issues.apache.org/jira/browse/HIVE-19941
             Project: Hive
          Issue Type: Bug
            Reporter: Nishant Bangarwa
            Assignee: Nishant Bangarwa


Issue is that when applying table mask we add virtual columns, however 
non-native tables do not have virtual columns, we need to skip adding virtual 
columns when generating masking query. 

Stack Trace -
