Discovering Native Clients
Hazelcast members and native Java clients can find each other with multicast discovery plugin. This plugin is implemented using Hazelcast Discovery SPI. You should configure the plugin both at Hazelcast members and Java clients in order to use multicast discovery.
To configure your cluster to have the multicast discovery plugin, follow these steps:
enabledattribute of the
Add multicast discovery strategy configuration to your XML file, i.e.,
The following is an example declarative configuration.
<hazelcast> ... <properties> <property name="hazelcast.discovery.enabled">true</property> </properties> <network> <join> <discovery-strategies> <discovery-strategy class="com.hazelcast.spi.discovery.multicast.MulticastDiscoveryStrategy" enabled="true"> <properties> <property name="group">220.127.116.11</property> <property name="port">54327</property> </properties> </discovery-strategy> </discovery-strategies> </join> </network> ... </hazelcast>
hazelcast: properties: hazelcast.discovery.enabled: true network: join: discovery-strategies: discovery-strategy: enabled: true class: com.hazelcast.spi.discovery.multicast.MulticastDiscoveryStrategy properties: group: 18.104.22.168 port: 54327
The following are the multicast discovery plugin configuration properties with their descriptions:
group: String value that is used to set the multicast group, so that you can isolate your clusters.
port: Integer value that is used to set the multicast port.
