Using Ignite 2.11 and the following code works.
Server:
public class ComputeServer {
public static void main(String[] args) {
IgniteConfiguration igniteConfiguration = new IgniteConfiguration()
.setPeerClassLoadingEnabled(true);
Ignite ignite = Ignition.start(igniteConfiguration);
}
}
Client:
public class ComputeClient {
public static void main(String[] args) {
IgniteConfiguration igniteConfiguration = new IgniteConfiguration()
.setClientMode(true)
.setPeerClassLoadingEnabled(true);
try (Ignite ignite = Ignition.start(igniteConfiguration)) {
ignite.compute().run(() -> System.out.println("Hello, world"));
}
}
}
(It executes on server nodes by default; you don’t need to create a cluster
group for that.)
So I think you’ll need to share more about your configuration and/or code to
get to the bottom of this.
