Thank you for the quick response. First of wall ,none of the servers have a
firewall. And all the ignite instances are run as root, on machines that I
solely run for ignite. So I really don't understand How they can have any
connection permission problems at all.
For now , I'll also provide the small java snippet I run for this test:
IgniteConfiguration cfg = new IgniteConfiguration();
cfg.setClientMode(true);
cfg.setPeerClassLoadingEnabled(true);
cfg.setWorkDirectory("/tmp/");
TcpDiscoveryVmIpFinder ipFinder = new TcpDiscoveryVmIpFinder();
ipFinder.setAddresses(Arrays.asList("51.15.203.48","51.15.88.216"));
cfg.setDiscoverySpi(new
TcpDiscoverySpi().setLocalAddress("68.183.91.137").setIpFinder(ipFinder));
Ignite ignite=Ignition.start(cfg);
