------------------------------------------
Summary: Add a built in function to determine if a user is in a
given role
Key: IMPALA-5332
URL: https://issues.apache.org/jira/browse/IMPALA-5332
Project: IMPALA
Issue Type: Improvement
Reporter: Christopher Royles
It is possible to get the user() and effective_user(), however it is not
possible to determine the users role.
Implement a mechanism to test that a user is within a certain role.
This function should return inline and be efficient.
Should be testable within a WHERE clause, providing per row-filtering within a
view or query.
Alternatively provide a mechanism where the SHOW CURRENT ROLES function returns
a table that can be used inline as a join with other tables.
