             Summary: Ranger-admin not showing presto columns
                 Key: RANGER-2501
                 URL: https://issues.apache.org/jira/browse/RANGER-2501
             Project: Ranger
          Issue Type: Bug
          Components: plugins
    Affects Versions: 2.0.0
            Reporter: Pedro Gonçalves Rossi Rodrigues


The RangerSystemAccessControl (https://github.com/apache/ranger/blob/master/ranger-presto-plugin-shim/src/main/java/org/apache/ranger/authorization/presto/authorizer/RangerSystemAccessControl.java) which Presto invokes doesn't have a fundamental method that its interfaces defaults to deny *checkCanShowColumnsMetadata* ([https://github.com/prestosql/presto/blob/master/presto-spi/src/main/java/io/prestosql/spi/security/SystemAccessControl.java#L209)] resulting in the fact that the Ranger-Admin cannot list any columns in the interface for the user.
