（3）现在我想连接到elasticsearch

1.3.2

名为

shaharma

的集群，如下所示

@Override
public Client getObject() throws Exception {
    this.client = nodeBuilder()
            .clusterName("shaharma")
            .client(true)
            .build()
            .start()
            .client();

    return client;
}

但是，从应用程序中找不到上面已经运行的

clusterName

shaharma

，而是从

9202

和

9302

开始

}

由于应用程序无法连接到elasticsearch，它会给出MasterNotDiscovery

org.elasticsearch.discovery.MasterNotDiscoveryException:等待[1m]

localhostip中完全相同的场景运行正常，因为应用程序节点下方的日志检测到已在运行的节点具有相同的

因此，我的问题是，如何使应用程序能够在具有动态ip（使用elasticsearch NodeClient）的机器中检测已经运行的elasticsearch集群。 工具书类

---

进行以下更改可以解决此问题，但不确定这是否是最好的解决方案，而不是使用机器的实际ip

（1）在

config/elasticsearch.yaml

中更改

network.host

network.host: 127.0.0.1

（2）从

节点客户端

显式设置

网络主机

public Client getObject() throws Exception {
    this.client = nodeBuilder()
            .settings(ImmutableSettings.settingsBuilder()
                         .put("cluster.name", "shaharma")
                         .put("network.host", "127.0.0.1"))
            .client(true)
            .build()
            .start()
            .client();

    return client;
}
