there is no way to declare an attribute as final). It is the responsibility
of the author of the configuration file (and their tools) to detect such

+### Key Application Configuration Items
+The following sections provides details about certain application
configuration properties that can be utilized to tailor the deployment of a
given application:
+
+#### Controlling assigned port ranges
+For certain deployments, the ports available for communication with clients
(Web UI ports, RPC ports, etc) are restricted to a specific set (e.g when
leveraging a firewall). In those situations you can designate the set of
allowed ports with the "site.global.slider.allowed.ports" setting. This
settings takes a comma-delimited set of port numbers and ranges, e.g.:
+
+ "site.global.slider.allowed.ports": "48000, 49000, 50001-50010"
+
+The AM exposed ports (Web UI, RPC), as well as the ports allocated to launched
application containers, will be limited to the ranges specified by the property
value.
+
+#### Delaying container launch
+In situations where container restarts may need to be delayed to allow for
platform resources to be released (e.g. a port assigned to a container that is
stopped may be slow to release), a delay can be designated by setting the
"container.launch.delay.sec" property in the component's configuration section:
+
+ "worker": {
+ "jvm.heapsite": "512M",
+ "container.launch.delay.sec": "30"
+ }
