Hello, I think I have this question in a few different threads but still no answer ;-)
What ports need to be open on machines so that an ignite cache cluster can be functional? I am getting these errors in the logs of my 5 machine ignite "cluster" on EC2 (code works on a single machine) - the scala code using the cluster is using it via setClientMode(true): [08:49:57,648][INFO][disco-event-worker-#46%null%][GridDiscoveryManager] Topology snapshot [ver=980, nodes=6, CPUs=40, heap=6.3GB] [08:49:57,649][WARNING][disco-event-worker-#46%null%][GridDiscoveryManager] Node FAILED: TcpDiscoveryNode [id=a4cc9d13-e595-4b94-9b3d-2bd0a9b23d2c, addrs=[10.10.212.123, 127.0.0.1], sockAddrs=[dev-ognen.vpc/ 10.10.212.123:47501, /10.10.212.123:47501, /127.0.0.1:47501], discPort=47501, order=980, intOrder=493, loc=false, ver=1.0.0#20150328-sha1:5fc2cd05, isClient=false] [08:49:57,649][INFO][disco-event-worker-#46%null%][GridDiscoveryManager] Topology snapshot [ver=981, nodes=5, CPUs=40, heap=5.0GB] [08:49:59,765][WARNING][grid-time-coordinator-#48%null%][TcpCommunicationSpi] Failed to connect to a remote node (make sure that destination node is alive and operating system firewall is disabled on local and remote hosts) [addrs=[/127.0.0.1:47101, dev-ognen.vpc/10.10.212.123:47101, / 10.10.212.123:47101]] So far I have iptables set up to allow the following ports: ACCEPT udp -- anywhere anywhere udp dpt:31100 ACCEPT udp -- anywhere anywhere udp dpt:47400 ACCEPT tcp -- anywhere anywhere tcp dpt:47500 ACCEPT tcp -- anywhere anywhere tcp dpt:47100 Is there anything I am missing? Is it port 47101 that needs to be open? If so, does it need to be open on all the machines in the "cluster"? I am happy to write up a guide on how to set these things up on Amazon (for example) but I need some help/guidance... Thanks! Ognen
