PK,

If you have access to the Sentry Store backend use a query like this:

SELECT
r.ROLE_NAME,
g.GROUP_NAME,
p.*,
FROM_UNIXTIME(p.CREATE_TIME / 1000) as CREATE_TIME_DATE
FROM
SENTRY_ROLE r
INNER JOIN SENTRY_ROLE_GROUP_MAP rgm ON r.ROLE_ID = rgm.ROLE_ID
INNER JOIN SENTRY_GROUP g ON g.GROUP_ID = rgm.GROUP_ID
INNER JOIN SENTRY_ROLE_DB_PRIVILEGE_MAP rpm ON r.ROLE_ID = rpm.ROLE_ID
INNER JOIN SENTRY_DB_PRIVILEGE p ON p.DB_PRIVILEGE_ID = rpm.DB_PRIVILEGE_ID;

Hope it helps,

Use the following command reference

These are to be executed from Hive Beeline to view Role Privileges and Assignments

> SHOW ROLES;
List available roles

> SHOW CURRENT ROLES;
List roles assigned to current user/group

> SHOW ROLE GRANT GROUP <GROUP NAME>;
Lists the roles that are assigned to the specified group.

> SHOW GRANT ROLE <ROLE>;
Lists the permissions that have been granted to the specified role.

>SHOW GRANT ROLE <role name> ON <object type> <object name>
Lists the permissions that a role has on an object.

Hi,

Thank you for the reply, but if I know the role or group, I can easily get the details from above commands, but for a specific DB , if I want to find out what are the roles assigned, is there a way to do it ?

Assume, my schema name is schema1, how to find out the roles assigned to this schema ?

Thank you.

PK

Hello @JoseManuel ,

Is there any possible query to have a similar result with Ranger (CDP 7.1.7 sp2)?
