*** KMS Proxyuser Configuration
Each proxyusers must be configured in <<<etc/hadoop/kms-site.xml>>> using the
following properties:
+---+
<property>
<name>hadoop.kms.proxyusers.#USER#.users</name>
<value>*</value>
</property>
<property>
<name>hadoop.kms.proxyusers.#USER#.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.kms.proxyusers.#USER#.hosts</name>
<value>*</value>
</property>
+---+
<<<#USER#>>> is the username of the proxyuser to configure.
The <<<users>>> property indicates the users that can be impersonated.
The <<<groups>>> property indicates the groups users being impersonated must
belong to.
At least one of the <<<users>>> or <<<groups>>> properties must be defined.
If both are specified, then the configured proxyuser will be able to
impersonate and user in the <<<users>>> list and any user belonging to one of
the groups in the <<<groups>>> list.
The <<<hosts>>> property indicates from which host the proxyuser can make
impersonation requests.
If <<<users>>>, <<<groups>>> or <<<hosts>>> has a <<<*>>>, it means there are
no restrictions for the proxyuser regarding users, groups or hosts.
*** KMS over HTTPS (SSL)
