问题
我刚使用docker搭建了单FE单BE的集群，查看用户时，出现了标题所说的输出：
MySQL [information_schema]> show all grants;
+--------------+----------+-------------------------------+--------------+---------------+------------+---------------+
| UserIdentity | Password | GlobalPrivs | CatalogPrivs | DatabasePrivs | TablePrivs | ResourcePrivs |
+--------------+----------+-------------------------------+--------------+---------------+------------+---------------+
| 'root'@'%' | No | Node_priv Admin_priv (false) | NULL | NULL | NULL | NULL |
| 'admin'@'%' | No | Admin_priv (false) | NULL | NULL | NULL | NULL |
+--------------+----------+-------------------------------+--------------+---------------+------------+---------------+
2 rows in set (0.001 sec)
同时查看角色时，发现存在权限重复的情况，如”Admin_priv Admin_priv“：
MySQL [information_schema]> show roles;
+----------+-------------+---------------------------------------------+--------------+---------------+------------+---------------+
| Name | Users | GlobalPrivs | CatalogPrivs | DatabasePrivs | TablePrivs | ResourcePrivs |
+----------+-------------+---------------------------------------------+--------------+---------------+------------+---------------+
| admin | 'admin'@'%' | Admin_priv Admin_priv | NULL | NULL | NULL | NULL |
| operator | 'root'@'%' | Node_priv Admin_priv Node_priv Admin_priv | NULL | NULL | NULL | NULL |
+----------+-------------+---------------------------------------------+--------------+---------------+------------+---------------+
2 rows in set (0.002 sec)
请问这样输出的原因是什么？
