我一直在尝试在Elastic-Search中创建一个TrasportClient，但不知何故无法运行它。
Java代码：
package es_example.custom;
import org.elasticsearch.action.index.IndexResponse;
import org.elasticsearch.client.Client;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.settings.Settings;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.node.NodeBuilder;
import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.HashMap;
import java.util.Map;
public class EsRoutingTransportClient
{
// Both the IP addresses are replaced with valid IP addresses in code
String ZEN_DISCOVERY_UNICAST_HOSTS_NO_JSON = "10.100.100.100,10.111.111.111";
String ES_PATH_HOME = "/app/devuser/elasticsearch/dummy-path-home/";
String ES_CLUSTER_NAME = "my-cluster"; // Verified cluster exists
Integer ES_PORT = 9200;
private Client client;
public EsRoutingTransportClient()
{
String elasticSearchHost = ZEN_DISCOVERY_UNICAST_HOSTS_NO_JSON;
Integer defaultPort = ES_PORT;
String elasticSearchCluster = ES_CLUSTER_NAME;
Settings settings = Settings.settingsBuilder()
.put("http.enabled", true)
.put("discovery.zen.ping.multicast.enabled", false)
// Both the IP addresses are replaced with valid IP addresses in code
.put("discovery.zen.ping.unicast.hosts", "[\"10.100.100.100\",\"10.111.111.111\"]")
.put("discovery.zen.minimum_master_nodes", 1)
.put("path.home", ES_PATH_HOME)
.build();
client = TransportClient.builder().settings(settings).build();
parseAndAddHostPort(elasticSearchHost, defaultPort);
}
private void parseAndAddHostPort(String elasticSearchHost, Integer defaultPort)
{
String [] esHosts = elasticSearchHost.split(",");
for (String esHost: esHosts)
{
String [] hostPort = esHost.split(":");
Integer esPort = defaultPort;
if (hostPort.length == 2)
{
esHost = hostPort[0];
esPort = Integer.parseInt(hostPort[1]);
}
try
{
client = ((TransportClient)client).addTransportAddress(
new InetSocketTransportAddress(InetAddress.getByName(esHost), esPort));
System.out.println("Added " + esHost + " with port " + esPort + " as a transport address");
} catch (UnknownHostException e) {
e.printStackTrace();
}
}
}
public void sendMessage (String msg, String indexName, String type, String id, String routing)
{
try
{
byte[] byteBuffer = msg.getBytes();
IndexResponse response = client.prepareIndex(indexName, type, id)
.setSource(byteBuffer)
.execute()
.actionGet();
}
catch (Exception e)
{
e.printStackTrace();
}
}
public static void main (String args[])
{
EsRoutingTransportClient esClient = new EsRoutingTransportClient();
esClient.sendMessage("Hello", "storm", "json-trips", null, null);
}
}

我按如下方式运行：
mvn clean package
java -jar target/es-proj-0.0.3-SNAPSHOT.jar
这是我得到的例外：

Ping两个主机都在同一个终端上工作。
（我在上面的例子中使用了10.100.100.100和10.111.111.111。实际上是代码库，它们是真正有效的IP地址）
上面列表中提到的节点之一也是master，另一个是数据节点。
我不知道如何解决这个问题。
非常感谢任何帮助。
谢谢！
答案 0 :(得分：1)
您为TransportClient创建的设置不正确。它们都应该是ES节点上elasticsearch.yml文件中的设置。这些是配置ES服务器的设置，而不是ES TransportClient。
因此，需要在10.100.100.100和10.111.111.111上运行的节点上的elasticsearch.yml文件中设置以下设置
cluster.name: my-cluster
http.enabled: true
discovery.zen.ping.multicast.enabled: false
discovery.zen.ping.unicast.hosts: ["10.100.100.100","10.111.111.111"]
discovery.zen.minimum_master_nodes: 1
path.home: /path/to/es/home
此外，您还需要在每个主机上设置以下设置及其正确的IP地址（即每个主机将绑定的IP地址，以便其他节点和客户端可以看到它们并连接到它们）：
network.host: 10.100.100.100
然后你可以像这样构建你的ES客户端：
Settings settings = Settings.settingsBuilder().build();
client = TransportClient.builder().settings(settings).build();
parseAndAddHostPort(elasticSearchHost, defaultPort);
这应该有效。
