 == Packages Inspected during Serialization
 
 When a session is serialized, Kubernetes Kit inspects classes for transient fields that can be injected during deserialization (see <<session-replication#,session replication>>).

-The `service-name` property defines the name of the Hazelcast service deployment within a cluster.
+The `service-name` and `service-port` properties defines the endpoint of the Hazelcast service deployment within a cluster.
+If `service-port` is specified with a value greater than 0, it overrides the default Hazelcast port (5701).
 
 The optional `namespace` property is used when the Hazelcast service is deployed in a namespace other than `default`.

+[NOTE]
+====
+By default, Hazelcast installs a shutdown hook to stop the instance when the JVM shuts down.
+Kubernetes Kit requires the shutdown hook to be disabled to ensure that the latest session state can be persisted when the application stops.
+The Kit automatically applies the configuration; however, if the application provides a custom `HazelcastInstance` bean, it is important that it is configured with `hazelcast.shutdownhook.enabled=false`. A warning message is printed on the console at startup if the shutdown hook is enabled.
+Spring takes care of automatically gracefully stop the Hazelcast instance when the bean is destroyed.
