In the course of testing the usersync tool, we had some settings wrong and the users are mis-synced. We'd like to clear them all out and restart the sync. Is there an easy way/tool to remove all the external users from the Ranger / Ranger usersync database so we can resync with our new settings?

@bganesan Now that https://issues.apache.org/jira/browse/RANGER-205 is fixed, can we use the rest API instead of DB script?

Really useful scripts. Helped me with my MySQL environment.
To prepare the input.txt, I had to run this and pass this as input to the script:
$ mysql -u userName -p dbName -e “select user_name from x_user” > /tmp/input.txt

Awesome! These API urls were really helpful!
You have to make sure the user or group is not assigned to any policy before you delete it. If the user/group is assigned to a policy the API returns 404 not found as result.

Until the API gets fixed to clean things up correctly, here's a PostgreSQL anonymous code block which cleans up the stuff it leaves behind which we used:
DO $ DECLARE u record; r record; p record; BEGIN FOR u IN select id, login_id from x_portal_user where login_id not in (select user_name from x_user) LOOP RAISE NOTICE 'User roles in x_portal_user_role:'; FOR r IN select id, user_id, user_role from x_portal_user_role where user_id = u.id LOOP RAISE NOTICE USING MESSAGE = ' ' || r.user_role; RAISE NOTICE USING MESSAGE = 'DELETE from x_portal_user_role WHERE id = ' || r.id; -- Uncomment next line to perform action --EXECUTE 'DELETE from x_portal_user_role WHERE id = ' || r.id; END LOOP; RAISE NOTICE 'User permissions in x_user_module_perm:'; FOR p IN select id, user_id, module_id from x_user_module_perm where user_id = u.id LOOP RAISE NOTICE USING MESSAGE = ' ' || (select module from x_modules_master where id = p.module_id); RAISE NOTICE USING MESSAGE = 'DELETE from x_user_module_perm where id = ' || p.id; -- Uncomment next line to perform action --EXECUTE 'DELETE from x_user_module_perm where id = ' || p.id; END LOOP; RAISE NOTICE USING MESSAGE = 'DELETE FROM x_portal_user WHERE id = ' || u.id; -- Uncomment next line to perform action --EXECUTE 'DELETE FROM x_portal_user WHERE id = ' || u.id; RAISE NOTICE ' '; END LOOP; END$;

For complete cleaning of users from DB, please use the scripts provided by @bganesan@hortonworks.com above.
REST API DELETE calls perform only soft-delete.
Hard DELETE feature is still in the works.https://issues.apache.org/jira/browse/RANGER-205
