the ability to refresh the service-level authorization configuration to

** Access Control using list of ip addresses, host names and ip ranges
Access to a service can be controlled based on the ip address of the client accessing
the service. It is possible to restrict access to a service from a set of machines by
specifying a list of ip addresses, host names and ip ranges. The property name for each service
is derived from the corresponding acl's property name. If the property name of acl is
security.client.protocol.acl, property name for the hosts list will be
security.client.protocol.hosts.
If hosts list is not defined for a service, the value of
<<<security.service.authorization.default.hosts>>> is applied. If
<<<security.service.authorization.default.hosts>>> is not defined, <<<*>>> is applied.
It is possible to specify a blocked list of hosts. Only those machines which are in the
hosts list, but not in the blocked hosts list will be granted access to the service. The property
name is derived by suffixing with ".blocked".
Example: The property name of blocked hosts list for <<<security.client.protocol.hosts>>
will be <<<security.client.protocol.hosts.blocked>>>
If blocked hosts list is not defined for a service, the value of
<<<security.service.authorization.default.hosts.blocked>>> is applied. If
<<<security.service.authorization.default.hosts.blocked>>> is not defined,
empty blocked hosts list is applied.
** Examples
Allow only users <<<alice>>>, <<<bob>>> and users in the <<<mapreduce>>> group to submit
