Apache Ignite Quick Start Guide

Local nodes

To work with the local node, you need to get the local ClusterGroup:

public class LocalNodes { public static void main(String[] args) {     IgniteConfiguration cfg = new IgniteConfiguration();     cfg.setPeerClassLoadingEnabled(true);         try (Ignite ignite = Ignition.start(cfg)) {             IgniteCluster cluster = ignite.cluster();              //Get local server group             ClusterGroup forLocal = cluster.forLocal();              //Get a compute task for local servers             IgniteCompute compute = ignite.compute(forLocal);              //broadcast the computation to local nodes             compute.broadcast(() -> {                 System.out.println("********\r\nLocal Only\r\n*********");             });         }     }}

It prints the message to the local program console only:
