Code in JAVA Spring BOOT

      boolean enableSsl = true;
    Settings settings = Settings.builder()
            .put("client.transport.nodes_sampler_interval", "5s")
            .put("client.transport.sniff", false)
            .put("transport.tcp.compress", true)
            .put("cluster.name", clusterName)
            .put("xpack.security.transport.ssl.enabled", enableSsl)
            .put("request.headers.X-Found-Cluster", "${cluster.name}")
            .put("xpack.security.user", System.getProperty("xpack.security.user"))
            .put("xpack.security.transport.ssl.verification_mode", insecure ? "none" : "full")
            .build();

    String hostname = "7c12baf8da6b4c1da553c7557a004844.us-east-1.aws.found.io";
    try {

        System.out.println("CONNECT");
        TransportClient myclient = new PreBuiltTransportClient(settings)
                .addTransportAddress(new TransportAddress(InetAddress.getByName(hostname), 9343));

    }catch (Exception e){
        e.printStackTrace();
    }

getting the exception

First you need to use the same client version as the server. 6.5.4 and not 6.0.0.

Shyju_M · January 23, 2019, 10:33am

Getting another exception with the below code changes

 boolean enableSsl = true;
    String clusterId = "7c12baf8da6b4c1da553c7557a004844"; // Your cluster ID here

    String region = "us-east-1";
    Settings settings = Settings.builder()
            .put("client.transport.nodes_sampler_interval", "5s")
            .put("client.transport.sniff", false)
            .put("transport.tcp.compress", true)
            .put("cluster.name", clusterName)
            .put("xpack.security.transport.ssl.enabled", enableSsl)
            .put("request.headers.X-Found-Cluster", clusterId)
            .put("xpack.security.user", "elastic:pass")
            .put("xpack.security.transport.ssl.verification_mode", insecure ? "none" : "full")
            .build();
    String hostname = clusterId + "." + region + ".aws.found.io";
    try {

        System.out.println("CONNECT");
        TransportClient myclient = new PreBuiltTransportClient(settings)
                .addTransportAddress(new TransportAddress(InetAddress.getByName(hostname), 9343));

    }catch (Exception e){
        e.printStackTrace();
    }

exception

Kindly Help @dadoonet

Shyju_M · January 23, 2019, 10:35am

@dadoonet. Thank you, I will update the same but it was working fine with the local elastic server

dadoonet · January 23, 2019, 10:36am

Then you need to read: https://www.elastic.co/guide/en/elasticsearch/reference/6.5/setup-xpack-client.html

https://www.elastic.co/guide/en/elastic-stack-overview/6.5/java-clients.html

Shyju_M · January 23, 2019, 10:47am

That is already added to the pom.xml file The version is correct or not please

	<dependency>
		<groupId>org.elasticsearch.client</groupId>
		<artifactId>x-pack-transport</artifactId>
		<version>6.5.4</version>
	</dependency>

Shyju_M · January 23, 2019, 11:02am

@dadoonet I could see the below item in the documentation

Kindly have a look and guide me to resolve the same

 java.lang.IllegalArgumentException: empty text

The exception is typically seen when a https request is made to a node that is not using https. If https is desired, please ensure the following setting is in elasticsearch.yml:

xpack.security.http.ssl.enabled: true

https://www.elastic.co/guide/en/x-pack/5.4/security-troubleshooting.html

dadoonet · January 23, 2019, 11:09am

Don't read old documentation. https://www.elastic.co/guide/en/x-pack/5.4/security-troubleshooting.html is for 5.4.

There is an example of a 6.2 version which I hope is still accurate:

But you should NOT be using the transport client anyway but the REST Client instead.

Shyju_M · January 24, 2019, 9:51am

Thank you very much I could connect with the below code

public class ElasticsearchConfig {


@Value("${elasticsearch.host}")
private String host;

@Value("${elasticsearch.port}")
private int port;

@Value("${elasticsearch.username}")
private String userName;

@Value("${elasticsearch.password}")
private String password;

@Bean(destroyMethod = "close")
public RestHighLevelClient client() {

    final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
    credentialsProvider.setCredentials(AuthScope.ANY,
            new UsernamePasswordCredentials(userName, password));

    RestClientBuilder builder = RestClient.builder(new HttpHost(host, port))
            .setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider));

    RestHighLevelClient client = new RestHighLevelClient(builder);


    return client;

}

}
