             Summary: Add a Hive condition to restrict access to mutually exclusive columns
                 Key: RANGER-619
                 URL: https://issues.apache.org/jira/browse/RANGER-619
             Project: Ranger
          Issue Type: Bug
          Components: plugins
    Affects Versions: 0.5.0
            Reporter: Madhan Neethiraj
            Assignee: Abhay Kulkarni


It should be possible to restrict queries that access specified columns together. For example, users should not be able run a query (such as the one given below) that access these columns together: employee.emp_id and payroll.emp_id:

select emp.name, pay.salary from employee emp, payroll pay where emp.emp_id = pay.emp_id;

However, it should be possible to allow such queries for certain users/groups - for example, auditors/finance.
