Client application written in Java and running in kubernetes. Following is the configuration for client.
IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setClientMode(true);
cfg.setShutdownPolicy(ShutdownPolicy.GRACEFUL);
KubernetesConnectionConfiguration connectionConfiguration = new KubernetesConnectionConfiguration();
connectionConfiguration.setNamespace(System.getenv("NAMESPACE"));
connectionConfiguration.setServiceName(System.getenv("SERVICE_NAME"));
TcpDiscoveryKubernetesIpFinder ipFinder = new TcpDiscoveryKubernetesIpFinder(connectionConfiguration);
cfg.setMetricsLogFrequency(0);
cfg.setDiscoverySpi(new TcpDiscoverySpi().setIpFinder(ipFinder));
ignite = Ignition.start(cfg);
No server side error in this time. What is the reason for this and how I solve this without breaking existing caches and data.
