-------------------------------------

             Summary: no privileges for select count(*) but select * works 
                 Key: IMPALA-9259
                 URL: https://issues.apache.org/jira/browse/IMPALA-9259
             Project: IMPALA
          Issue Type: Bug
          Components: Frontend, Security
            Reporter: Xiaomin Zhang


When authorization enabled, Impala rejects count(*) but select * still works. This happens when the role is only granted all columns privileges, but without SELECT on the table.
