** Blocked Access Control Lists
In some cases, it is required to specify blocked access control list for a service. This specifies
the list of users and groups who are not authorized to access the service. The format of
the blocked access control list is same as that of access control list. The blocked access
control list can be specified via <<<${HADOOP_CONF_DIR}/hadoop-policy.xml>>>. The property name
is derived by suffixing with ".blocked".
Example: The property name of blocked access control list for <<<security.client.protocol.acl>>
will be <<<security.client.protocol.acl.blocked>>>
For a service, it is possible to specify both an access control list and a blocked control
list. A user is authorized to access the service if the user is in the access control and not in
the blocked access control list.
If blocked access control list is not defined for a service, the value of
<<<security.service.authorization.default.acl.blocked>>> is applied. If
<<<security.service.authorization.default.acl.blocked>>> is not defined,
