             Summary: Make sure partial invoke only applies to explicit privileges
                 Key: SENTRY-2161
                 URL: https://issues.apache.org/jira/browse/SENTRY-2161
             Project: Sentry
          Issue Type: Sub-task
            Reporter: Na Li


*Background:*
Partial revoke
For examples:
1. When a role has been granted "all" on table and the role already has select/insert on privileges, they are removed automatically as "all" covers the "select/insert".
2. When a role already has "all" privileges on a table and "select" privilege are revoked, "all" privileges is revoked and "insert" is added automatically as there are only "select", "insert", and "all".

Hierarchical privileges:
Revoking privilege on a database would effect the privileges granted to the tables in that database.

*Problem:*
For example: 
1) User_A has "select" on table_B
2) User_A is set to owner of table_B and gets "all" privilege on table_B as implicit privilege
3) User_A is not owner of table_B any more

based on partial invoke behavior, User_A will lose "select" on table_B after step 3). The desired behavior is for User_A still retains "select" on table_B after step 3)

*Solution:*

Only apply partial revoke to user configured privileges (explicit privilege), and not affect implicit privileges.
