I have a test that uses the embedded node. It works well usually with Data-less node and HTTP API. I have a problem when I run a test using TransportClient to connect to the other node (on the same JVM), I get: org.elasticsearch.transport.ConnectTransportException: [][inet[/127.0.0.1:9300]] connect\_timeout[30s] at org.elasticsearch.transport.netty.NettyTransport.connectToChannelsLight(NettyTransport.java:683) at org.elasticsearch.transport.netty.NettyTransport.connectToNode(NettyTransport.java:643) at org.elasticsearch.transport.netty.NettyTransport.connectToNodeLight(NettyTransport.java:610) at org.elasticsearch.transport.TransportService.connectToNodeLight(TransportService.java:133) at org.elasticsearch.client.transport.TransportClientNodesService$SimpleNodeSampler.doSample(TransportClientNodesService.java:355) at org.elasticsearch.client.transport.TransportClientNodesService$NodeSampler.sample(TransportClientNodesService.java:301) at org.elasticsearch.client.transport.TransportClientNodesService.addTransportAddresses(TransportClientNodesService.java:169) at org.elasticsearch.client.transport.TransportClient.addTransportAddress(TransportClient.java:237) at com.netaporter.cms.estests.test.TransportClientTest.testTransportClient(TransportClientTest.java:18) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:47) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:44) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:271) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:70) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:238) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:63) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:236) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:53) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:229) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:27) at org.junit.runners.ParentRunner.run(ParentRunner.java:309) at org.junit.runner.JUnitCore.run(JUnitCore.java:160) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:74) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:202) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:65) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120) Caused by: java.net.ConnectException: Connection refused: /127.0.0.1:9300 which is strange because I set up the port with (on the embedded node): port = 11547; // User ports range 1024 - 49151 tcpport = 9300; settings.put("http.port", port); settings.put("transport.tcp.port", tcpport); the embedded node _is also local_. The transport client is as simple as: TransportClient client = new TransportClient(); client.addTransportAddress(new InetSocketTransportAddress( "127.0.0.1", getTcpPort())); ``` client.prepareIndex("test", "type").setSource("field", "value"). ``` execute().actionGet(); I tried both with 127.0.0.1 and localhost any ideas? A colleague has been able to have the TransportClient work with a remote machine, but not with localhost. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
