I am trying to setup an elasticsearch cluster with 3 nodes. I am using es version 5.1.2. The node details are as follows: node1: 10.248.9.42 node2: 10.242.235.167 node3: 10.88.28.33 The node1 configuration is as follows: [cluster.name](http://cluster.name): my-cluster-1 [node.name](http://node.name): node1 network.host: 0.0.0.0 transport.host: 10.248.9.42 transport.tcp.port: 9300 http.port: 9200 indices.query.bool.max\_clause\_count: 4096 discovery.zen.minimum\_master\_nodes: 2 discovery.zen.ping.unicast.hosts: ["10.248.9.42", "10.242.235.167", "10.88.28.33"] When I start elasticsearch on node1, it can start successfully. The node2 configuration is as follows: [cluster.name](http://cluster.name): my-cluster-1 [node.name](http://node.name): node2 network.host: 0.0.0.0 transport.host: 10.242.235.167 transport.tcp.port: 9300 http.port: 9200 indices.query.bool.max\_clause\_count: 4096 discovery.zen.minimum\_master\_nodes: 2 discovery.zen.ping.unicast.hosts: ["10.248.9.42", "10.242.235.167", "10.88.28.33"] When I try starting elasticsearch on node2, I am getting below error. What is going wrong here? org.elasticsearch.transport.BindTransportException: Failed to bind to [9300] at org.elasticsearch.transport.TcpTransport.bindToPort(TcpTransport.java:636) ~[elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.transport.TcpTransport.bindServer(TcpTransport.java:601) ~[elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.transport.netty4.Netty4Transport.doStart(Netty4Transport.java:182) ~[?:?] at org.elasticsearch.common.component.AbstractLifecycleComponent.start(AbstractLifecycleComponent.java:69) ~[elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.transport.TransportService.doStart(TransportService.java:188) ~[elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.common.component.AbstractLifecycleComponent.start(AbstractLifecycleComponent.java:69) ~[elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.node.Node.start(Node.java:577) ~[elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.bootstrap.Bootstrap.start(Bootstrap.java:234) ~[elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:308) [elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:121) [elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:112) [elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.cli.SettingCommand.execute(SettingCommand.java:54) [elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:122) [elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.cli.Command.main(Command.java:88) [elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:89) [elasticsearch-5.1.2.jar:5.1.2] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:82) [elasticsearch-5.1.2.jar:5.1.2] Caused by: java.net.BindException: Cannot assign requested address at sun.nio.ch.Net.bind0(Native Method) ~[?:1.8.0\_121] at sun.nio.ch.Net.bind(Net.java:433) ~[?:1.8.0\_121] at sun.nio.ch.Net.bind(Net.java:425) ~[?:1.8.0\_121] at sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:223) ~[?:1.8.0\_121] at io.netty.channel.socket.nio.NioServerSocketChannel.doBind(NioServerSocketChannel.java:127) ~[?:?] at io.netty.channel.AbstractChannel$AbstractUnsafe.bind(AbstractChannel.java:554) ~[?:?] at io.netty.channel.DefaultChannelPipeline$HeadContext.bind(DefaultChannelPipeline.java:1258) ~[?:?] at io.netty.channel.AbstractChannelHandlerContext.invokeBind(AbstractChannelHandlerContext.java:512) ~[?:?] at io.netty.channel.AbstractChannelHandlerContext.bind(AbstractChannelHandlerContext.java:497) ~[?:?] at io.netty.channel.DefaultChannelPipeline.bind(DefaultChannelPipeline.java:980) ~[?:?] at io.netty.channel.AbstractChannel.bind(AbstractChannel.java:250) ~[?:?] at io.netty.bootstrap.AbstractBootstrap$2.run(AbstractBootstrap.java:363) ~[?:?] at io.netty.util.concurrent.AbstractEventExecutor.safeExecute(AbstractEventExecutor.java:163) ~[?:?] at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:418) ~[?:?] at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:454) ~[?:?] at io.netty.util.concurrent.SingleThreadEventExecutor$5.run(SingleThreadEventExecutor.java:873) ~[?:?] at java.lang.Thread.run(Thread.java:745) ~[?:1.8.0\_121] [2017-04-21T00:29:57,688][WARN][o.e.b.ElasticsearchUncaughtExceptionHandler] [[slc12mun.us.oracle.com](http://slc12mun.us.oracle.com)] uncaught exception in thread [main] org.elasticsearch.bootstrap.StartupException: BindTransportException[Failed to bind to [9300]];

Hi, In all your configurations, remove "transport.host" entries, and just set "network.host": ``` network.host: ["10.242.235.167", "127.0.0.1"] # add or remove entries you need to bind ``` bye, Xavier ---

May I know why this change is necessary and what is wrong with my configuration? As I mentioned, elasticsearch is running fine in node1 with above configuration. ---

"transport.host" overwrite "network.host" setting. Does your node2 have a special connection ? ``` Cannot assign requested address bind0(Native Method) ~[?:1.8.0_121] ``` ---

Thanks. I did not get what you mean by- Does your node2 have a special connection? Please elaborate. ---
