Hello, I'm currently testing the graph api offered by X-pack. I could toy a bit with it using kibana, and wanted to test using it in my java application However, I'm stuck at the creation of the PreBuiltXPackTransportClient. Here's the creation code : > ``` > Settings settings = Settings.builder() > .put("cluster.name", "mycluster").build(); > > TransportClient client = new PreBuiltXPackTransportClient(settings); > try { > client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("myhost"), 9301)); > } catch (UnknownHostException e) { > // TODO Auto-generated catch block > e.printStackTrace(); > } > > ``` I'm getting this chain of errors > Exception in thread "main" ElasticsearchException[Failed to load plugin class [org.elasticsearch.xpack.XPackPlugin]]; nested: InvocationTargetException; nested: ElasticsearchException[failed to initialize a TrustManagerFactory]; nested: IOException[Keystore was tampered with, or password was incorrect]; nested: UnrecoverableKeyException[Password verification failed]; > at org.elasticsearch.plugins.PluginsService.loadPlugin(PluginsService.java:434) > at org.elasticsearch.plugins.PluginsService.(PluginsService.java:103) > at org.elasticsearch.client.transport.TransportClient.newPluginService(TransportClient.java:101) > at org.elasticsearch.client.transport.TransportClient.buildTemplate(TransportClient.java:126) > at org.elasticsearch.client.transport.TransportClient.(TransportClient.java:265) > at org.elasticsearch.transport.client.PreBuiltTransportClient.(PreBuiltTransportClient.java:130) > at org.elasticsearch.xpack.client.PreBuiltXPackTransportClient.(PreBuiltXPackTransportClient.java:55) > at org.elasticsearch.xpack.client.PreBuiltXPackTransportClient.(PreBuiltXPackTransportClient.java:50) > at org.elasticsearch.xpack.client.PreBuiltXPackTransportClient.(PreBuiltXPackTransportClient.java:46) > at application.TestGraph.main(TestGraph.java:22) > Caused by: java.lang.reflect.InvocationTargetException > at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) > at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) > at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) > at java.lang.reflect.Constructor.newInstance(Constructor.java:422) > at org.elasticsearch.plugins.PluginsService.loadPlugin(PluginsService.java:423) > ... 9 more > Caused by: ElasticsearchException[failed to initialize a TrustManagerFactory]; nested: IOException[Keystore was tampered with, or password was incorrect]; nested: UnrecoverableKeyException[Password verification failed]; > at org.elasticsearch.xpack.ssl.StoreTrustConfig.createTrustManager(StoreTrustConfig.java:57) > at org.elasticsearch.xpack.ssl.SSLService.createSslContext(SSLService.java:378) > at org.elasticsearch.xpack.ssl.SSLService.loadSSLConfigurations(SSLService.java:401) > at org.elasticsearch.xpack.ssl.SSLService.(SSLService.java:79) > at org.elasticsearch.xpack.XPackPlugin.(XPackPlugin.java:205) > ... 14 more > Caused by: java.io.IOException: Keystore was tampered with, or password was incorrect > at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:772) > at sun.security.provider.JavaKeyStore$JKS.engineLoad(JavaKeyStore.java:55) > at java.security.KeyStore.load(KeyStore.java:1445) > at org.elasticsearch.xpack.ssl.CertUtils.trustManager(CertUtils.java:168) > at org.elasticsearch.xpack.ssl.StoreTrustConfig.createTrustManager(StoreTrustConfig.java:55) > ... 18 more > Caused by: java.security.UnrecoverableKeyException: Password verification failed > at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:770) > ... 22 more However, I disabled x-pack security on my cluster. I do not understant why the client creation fails at a password verification if I do not have any security. The version I'm using is 5.5.1. Can anyone help me with any info on what I might be doing wrong? Thanks. ---

That error is referring to the password for your truststore. Is your application running with a system wide truststore defined? E.g. are you setting the `javax.net.ssl.trustStore` system property? ---

Hello, and thanks for answering. Yes, that property is set. It's set as a VM argument. And I tried to set it via System.setproperty as well, but still to no avail. ---

Well then you need to unset it, or also set the password for the truststore as a system property. If you run X-Pack with a system truststore then it needs the password too. ---

Thanks for the answer, and sorry for the delay. Yes, I get it, and that solves my problem. Thanks a lot. ---
