I am New in Elastic Search Java Api[5.0]. I am Using elasticsearch-5.0.0. I am try to create a Java Application(Maven) with Spring Boot. After run Application, it shows
2016-11-04 23:32:19.339 INFO 8280 --- [][generic][T#2]] org.elasticsearch.client.transport : [X-Ray] failed to get node info for [#transport#-1][DESKTOP-8SIPHSN][inet[localhost/127.0.0.1:9300]], disconnecting... org.elasticsearch.transport.NodeDisconnectedException: [][inet[localhost/127.0.0.1:9300]][cluster:monitor/nodes/info] disconnected
My Config File Is
@Configuration public class ElasticsearchConfiguration { @Bean public Client client() { TransportClient client = new TransportClient(); TransportAddress address = new InetSocketTransportAddress("localhost",9300); client.addTransportAddress(address); return client; } }
And I am using default cluster "elasticsearch". I need help to solve my issue with proper detection of causes.
Try using the PreBuiltTransportClient mentioned in the 5.0 documentation:
TransportClient client = new PreBuiltTransportClient(Settings.EMPTY) .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/transport-client.html
Also note that the TransportClient for ES version 2.x isn't compatible with 5.x:
The client must have the same major version (e.g. 2.x, or 5.x) as the nodes in the cluster. Clients may connect to clusters which have a different minor version (e.g. 2.3.x) but it is possible that new functionality may not be supported. Ideally, the client should have the same version as the cluster.

Update
As a connectivity test, try executing the following simple program:
import org.elasticsearch.client.transport.TransportClient; import org.elasticsearch.common.settings.Settings; import org.elasticsearch.common.transport.InetSocketTransportAddress; import org.elasticsearch.transport.client.PreBuiltTransportClient; import java.net.InetAddress; import java.net.UnknownHostException; public class App { public static void main(String[] args) throws UnknownHostException { // The following settings aren't strictly necessary, because the default cluster name is "elasticsearch". Settings settings = Settings.builder().put("cluster.name", "elasticsearch").build(); TransportClient client = new PreBuiltTransportClient(settings); client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300)); System.out.println(client.connectedNodes()); } }
It should print to stdout something like the following line:
[{luhcORJ}{luhcORJOSzSLPBeXocDsuQ}{mkTJpwIAQGuNYTHfRLqUIw}{127.0.0.1}{127.0.0.1:9300}]
