Hello, I have a problem connecting my 2 nodes with the same cluster. I have one VM with ES v5.3.1 and the other one v5.3.0. This my two files config : ``` cluster.name: "tsdb" node.name: "node-2" path.data: /var/lib/elasticsearch path.logs: /var/log/elasticsearch network.host: 10.60.74.38 discovery.zen.ping.unicast.hosts: ["mastervm"] discovery.zen.minimum_master_nodes: 2 discovery.zen.ping_timeout: 5s node.master: false node.data: false transport.tcp.port: 9300 http.port: 9200 http.enabled: true gateway.recover_after_nodes: 1 gateway.recover_after_time: 5m gateway.expected_nodes: 2 http.host: 10.60.74.38 bootstrap.system_call_filter: false ``` and the config for the master node : ``` cluster.name: "tsdb" node.name: "node-1" path.data: /var/lib/elasticsearch path.logs: /var/log/elasticsearch discovery.zen.ping.unicast.hosts: ["slavevm"] discovery.zen.minimum_master_nodes: 1 discovery.zen.ping_timeout: 5s node.master: true node.data: true transport.tcp.port: 9300 network.host: 10.50.0.222 http.port: 9200 http.enabled: true gateway.recover_after_nodes: 1 gateway.recover_after_time: 5m gateway.expected_nodes: 2 http.host: 0.0.0.0 cluster.routing.allocation.disk.threshold_enabled: false ``` Both of them are running but not connected. Concerning the logs , I have this : ``` [2017-04-28T13:07:08,423][WARN][o.e.d.z.ZenDiscovery] [node-2] failed to connect to master [{node-1}{kOu4qBYtQFOdBDn7JQ1qKg}{km6VaD8HQ5iPmHuf_8zi-g}{10.50.0.222}{10.50.0.222:9300}], retrying... org.elasticsearch.transport.ConnectTransportException: [node-1][10.50.0.222:9300] connect_timeout[30s] at org.elasticsearch.transport.netty4.Netty4Transport.connectToChannels(Netty4Transport.java:359) ~[?:?] at org.elasticsearch.transport.TcpTransport.openConnection(TcpTransport.java:495) ~[elasticsearch-5.3.1.jar:5.3.1] at org.elasticsearch.transport.TcpTransport.connectToNode(TcpTransport.java:460) ~[elasticsearch-5.3.1.jar:5.3.1] at org.elasticsearch.transport.TransportService.connectToNode(TransportService.java:314) ~[elasticsearch-5.3.1.jar:5.3.1] at org.elasticsearch.transport.TransportService.connectToNode(TransportService.java:301) ~[elasticsearch-5.3.1.jar:5.3.1] at org.elasticsearch.discovery.zen.ZenDiscovery.joinElectedMaster(ZenDiscovery.java:464) [elasticsearch-5.3.1.jar:5.3.1] at org.elasticsearch.discovery.zen.ZenDiscovery.innerJoinCluster(ZenDiscovery.java:416) [elasticsearch-5.3.1.jar:5.3.1] at org.elasticsearch.discovery.zen.ZenDiscovery.access$3800(ZenDiscovery.java:81) [elasticsearch-5.3.1.jar:5.3.1] at org.elasticsearch.discovery.zen.ZenDiscovery$JoinThreadControl$1.run(ZenDiscovery.java:1190) [elasticsearch-5.3.1.jar:5.3.1] at org.elasticsearch.common.util.concurrent.ThreadContext$ContextPreservingRunnable.run(ThreadContext.java:569) [elasticsearch-5.3.1.jar:5.3.1] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [?:1.8.0_121] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [?:1.8.0_121] at java.lang.Thread.run(Thread.java:745) [?:1.8.0_121] Caused by: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: 10.50.0.222/10.50.0.222:9300 at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method) ~[?:?] at sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:717) ~[?:?] at io.netty.channel.socket.nio.NioSocketChannel.doFinishConnect(NioSocketChannel.java:346) ~[?:?] at io.netty.channel.nio.AbstractNioChannel$AbstractNioUnsafe.finishConnect(AbstractNioChannel.java:340) ~[?:?] at io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:630) ~[?:?] at io.netty.channel.nio.NioEventLoop.processSelectedKeysPlain(NioEventLoop.java:527) ~[?:?] at io.netty.channel.nio.NioEventLoop.processSelectedKeys(NioEventLoop.java:481) ~[?:?] at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:441) ~[?:?] at io.netty.util.concurrent.SingleThreadEventExecutor$5.run(SingleThreadEventExecutor.java:858) ~[?:?] ``` Anyone can help me please.
