>                 Key: HIVE-28189
>                 URL: https://issues.apache.org/jira/browse/HIVE-28189
>             Project: Hive
>          Issue Type: Bug
>          Components: HiveServer2
>    Affects Versions: 3.1.0
>            Reporter: Yuping Fan
>            Priority: Major
>
> Due to the large number of permissions, the synchronization time exceeds 1 
> minute. 
> If I delete this table during that 1 minute, it will cause the table to fail 
> to delete, with the error that the tbl_col_privs foreign key constraint check 
> failed. So I think the table should be locked when the permissions are 
> synchronized
