Java Elasticsearch 5.1.2中的NoNodeAvailableException[所有配置的节点均不可用]
在Google Compute Engine上,我创建了3个虚拟机,并在其上安装了Java Elasticsearch 5.1.2中的NoNodeAvailableException[所有配置的节点均不可用],java,elasticsearch,google-compute-engine,Java,elasticsearch,Google Compute Engine,在Google Compute Engine上,我创建了3个虚拟机,并在其上安装了Elasticsearch 5.1.2。 我为单播发现安装了GCE发现插件 从我的本地web浏览器(Win7),我可以成功访问这些Elasticsearch节点。 在Google云平台上,我添加了接受tcp:9300、tcp:9200的防火墙规则 现在我想使用Java transport client与本地Java应用程序中的远程Elasticsearch节点进行对话。 我确信cluster.name是正确的 代码

我为单播发现安装了GCE发现插件
从我的本地web浏览器(Win7),我可以成功访问这些Elasticsearch节点。
在Google云平台上,我添加了接受tcp:9300、tcp:9200的防火墙规则
现在我想使用Java transport client与本地Java应用程序中的远程Elasticsearch节点进行对话。
我确信cluster.name
是正确的
代码和错误如下所示:
public class NativeClient {

public static Client createTransportClient() throws UnknownHostException {
Settings settings = Settings.builder().put("cluster.name", "elasticsearch").put("client.transport.sniff", true)
.build();
TransportClient client = new PreBuiltTransportClient(settings)
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("104.100.100.96"), 9300));
return client;
}
private final Node node = null;
private final Client client = null;
}
public class IndicesOperations {
private final Client client;
public IndicesOperations(Client client) {
this.client = client;
}
public boolean checkIndexExists(String name){
IndicesExistsResponse response=client.admin().indices().prepareExists(name).execute().actionGet();

}
}

编辑:
在google compute engine上部署java应用程序后,它可以访问在google compute engine上运行的elasticsearch实例。在这个应用程序中,我刚刚修改了InetAddress.getByName(“10.140.0.2”)
。在本地机器上部署时,我使用了该虚拟机的外部ip
我还需要修改什么才能在本地机器上运行它?我将虚拟机的
外部ip
附加到网络中。在elasticsearch.yml中发布\u host
属性,然后我可以访问远程虚拟机上运行的elasticsearch:
network.host: _gce_
network.publish_host: 104.100.100.96
cloud:
gce:
project_id: es-cloud
zone: asia-east1-b

我不太明白,但幸运的是它起作用了
