How to configure elasticsearch 5 TransportClient.

Now TransportClient is abstract class. I found only PreBuiltTransportClient, this is the new way to configure elasticsearch Client ?

回答1:

Yes, you can find that in the official documentation for 5.0 as well

Settings settings = Settings.builder()
   .put("cluster.name", "ElasticSearchClusterName");

TransportClient client = new PreBuiltTransportClient(settings)
        .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host1"), 9300))
        .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host2"), 9300));

It is worth nothing that the PreBuiltTransportClient is pre-configured with the following modules:

Netty3
Netty4
Reindex
Percolator
Mustache

Also make sure that you have a dependency on the transport artifact:

<dependency>
    <groupId>org.elasticsearch.client</groupId>
    <artifactId>transport</artifactId>
    <version>5.0.0-beta1</version>
</dependency>

First download respective jar file and keep that in lib folder and add them to build path. You can follow below code to configure it:

 Settings settings = Settings.builder()
    .put("cluster.name", "ElasticSearchClusterName")
    //.put("client.transport.sniff", true)
    //.put("shield.user", elasticUserName+":"+elasticPassword)
    .build();

TransportClient client = new PreBuiltTransportClient(settings)
                                  .addTransportAddress(new InetSocketTransportAddress(elasticHostOne, elasticTransportPort))
                                  .addTransportAddress(new InetSocketTransportAddress(elasticHostTwo, elasticTransportPort))
                                  .addTransportAddress(new InetSocketTransportAddress(elasticHostThree, elasticTransportPort));
