** 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,
empty blocked access control list is applied.

<name>yarn.scheduler.capacity.queue-mappings</name>
<value></value>
<description>
A list of mappings that will be used to assign jobs to queues
The syntax for this list is [u|g]:[name]:[queue_name][,next mapping]*
Typically this list will be used to map users to queues,
for example, u:%user:%user maps all users to queues with the same name
as the user.
</description>
</property>
<property>
<name>yarn.scheduler.capacity.queue-mappings-override.enable</name>
<value>false</value>
<description>
If a queue mapping is present, will it override the value specified
by the user? This can be used by administrators to place jobs in queues
that are different than the one specified by the user.
The default is false.
</description>
</property>
</configuration>
