不论是否在Java中提到集群名称，弹性搜索都会创建集群？

Question

我们在application.properties文件中提供的弹性搜索集群名称。如果Elasticsearch中没有该集群名称，它将创建一个新集群名称吗？

@Configuration
public class ElasticSearchConfiguration 
{
    @Value("${spring.data.elasticsearch.cluster-name}")
    private String clusterName;
    @Value("${spring.data.elasticsearch.cluster-nodes}")
    private String clusterNodes;
    @Bean
    public ElasticsearchTemplate elasticsearchTemplate() throws UnknownHostException 
    {
            String server = clusterNodes.split(":")[0];
            Integer port = Integer.parseInt(clusterNodes.split(":")[1]);
            Settings settings = Settings.settingsBuilder()
                .put("cluster.name", clusterName).build();
            client = TransportClient.builder().settings(settings).build()
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(server), port));
            return new ElasticsearchTemplate(client);
    }
}
