I am trying to run one of the Hazelcast-jet example over a Distributed System. My objective is to run code over Disributed System, Utilize Multiple machine's processing power. I have two Laptops connected via LAN. When I run this example in One Machine it works fine, to run it both system I Start Machine 1 and Machine 2 with only jet Instance. code on both Machines are,
Machine 1
public class PrimeFinder {
public static void main(String[] args) {
System.setProperty("hazelcast.logging.type", "log4j");
try {
JetConfig cfg = new JetConfig();
cfg.setInstanceConfig(new InstanceConfig().setCooperativeThreadCount(
Math.max(1, getRuntime().availableProcessors() / 2)));
cfg.setProperty("hazelcast.initial.min.cluster.size","3");
Jet.newJetInstance(cfg);
JetInstance jet = Jet.newJetInstance(cfg);
DAG dag = new DAG();
final int limit = 15_485_864;
Vertex generator = dag.newVertex("number-generator", new GenerateNumbersMetaSupplier(limit));
Vertex primeChecker = dag.newVertex("filter-primes", filterP(PrimeFinder::isPrime));
Vertex writer = dag.newVertex("writer", writeListP("primes"));
dag.edge(between(generator, primeChecker));
dag.edge(between(primeChecker, writer));
jet.newJob(dag).join();
IListJet<Integer> primes = jet.getList("primes");
List<Integer> sortedPrimes = primes.stream().sorted().limit(1000).collect(toList());
System.out.println("Found " + primes.size() + " primes.");
System.out.println("Some of the primes found are: " + sortedPrimes);
} finally {
Jet.shutdownAll();
}
}
private static boolean isPrime(int n) {
if (n <= 1) {
return false;
}
int endValue = (int) Math.sqrt(n);
for (int i = 2; i <= endValue; i++) {
if (n % i == 0) {
return false;
}
}
return true;
}

this.limit = limit;

int end = (i + 1) * localParallelism;
int mod = totalParallelism;
map.put(address, count -> range(start, end)
.mapToObj(index -> new GenerateNumbersP(range(0, limit).filter(f -> f % mod == index)))

}
return map::get;

}
@Override

}
}
}
Machine 2

Can anyone help me out what am I doing wrong?
You need to add the class to the JobConfig and pass it when submitting the pipeline:
JobConfig jobConfig = new JobConfig();
jobConfig.addClass(PrimeFinder.class);
jet.newJob(dag, jobConfig).join();
