Note that in case of the REVOKE statement, the DROP-BEHAVIOR option of CASCADE is not currently supported (which is in SQL standard). As a result, the revoke statement will not drop any dependent privileges. For details on CASCADE behavior, you can check the Postgres revoke documentation.
Examples:
| Code Block | ||
|---|---|---|
| ||
0: jdbc:hive2://localhost:10000/default> grant select on table secured_table to role my_role;
No rows affected (0.046 seconds)
0: jdbc:hive2://localhost:10000/default> revoke update, select on table secured_table from role my_role;
No rows affected (0.028 seconds) |
Notice that in Hive, unlike in standard SQL, USER or ROLE must be specified in the principal_specification.
Show Grant
| Code Block | ||
|---|---|---|

SHOW GRANT [principal_namespecification] ON (ALL | ([TABLE] table_or_view_name) |
...
;
principal_specification
: USER user
| ROLE role |
Currently any user can run this command. But this is likely to change in the future to allow users to see only their own privileges, and additional privileges would be needed to see privileges of other users.
