EXAMPLES
GRANT
The following examples demonstrate grant of a single privilege. A single GRANT statement can grant multiple privileges at the same scope by providing a comma-separated list of the privileges.
To grant the CLUSTER ADMIN privilege at global scope, replace the user specification ('USERNAME'@'HOSTNAME') in the following query to align to your requirements:
GRANT CLUSTER ADMIN
ON *.*
TO 'USERNAME'@'HOSTNAME';
For general guidance on privileges, see "Privileges".
REVOKE
The following examples demonstrate revoke of a single previously-granted privilege. A single REVOKE statement can revoke multiple privileges at the same scope by providing a comma-separated list of the privileges.
To revoke the CLUSTER ADMIN privilege at global scope, replace the user specification ('USERNAME'@'HOSTNAME') in the following query to align to your requirements:
REVOKE CLUSTER ADMIN
ON *.*
FROM 'USERNAME'@'HOSTNAME';
For general guidance on privileges, see "Privileges".
SHOW Output
A user's privileges can be displayed using the SHOW GRANTS statement.
If the CLUSTER ADMIN privilege is present, it will be shown as CLUSTER ADMIN in the output. For example:
SHOW GRANTS FOR 'app_user'@'192.0.2.%';
+------------------------------------------------------+
| Grants for app_user@192.0.2.% |
+------------------------------------------------------+
| GRANT CLUSTER ADMIN ON *.* TO 'app_user'@'192.0.2.%' |
+------------------------------------------------------+

An error message is raised if an operation fails due to insufficient privileges. For example:
ALTER CLUSTER REFORM;
ERROR 1045 (HY000): [11281] Permission denied: User "'USERNAME'@'HOSTNAME'" is missing CLUSTER ADMIN on *.*; transaction aborted
