azure - 如何连接到Azure上安装的多个节点的elasticsearch集群？如何获取elasticsearch端点？

Question

我已经从 Azure 市场安装了 3 个 Elastic Search 节点，任何节点都可以充当主节点。现在如何连接到集群？如果我有一个节点，我可以简单地使用其 IP 和端口(9200)，但这里我有 3 个节点，那么如何获取集群端点？谢谢

我就是这样做的，它对我来说效果很好:

public class ElasticsearchConfig {

    private Vector<String> hosts;

    public void setHosts(String hostString) {
        if(hostString == null || hostString.trim().isEmpty()) {
            return;
        }

        String[] hostParts = hostString.split(",");
        this.hosts = new Vector<>();
        Collections.addAll(this.hosts, hostParts);
    }
}

public class ElasticClient {

    private final ElasticsearchConfig config;

    private RestHighLevelClient client;

    public ElasticClient(ElasticsearchConfig config) {
        this.config = config;
    }

    public void start() throws Exception {

        HttpHost[] httpHosts = new HttpHost[config.getHosts().size()];
        config.getHosts()
                .stream()
                .map(host -> new HttpHost(host.split(":")[0], Integer.valueOf(host.split(":")[1])))
                .collect(Collectors.toList())
                .toArray(httpHosts);

        client = new RestHighLevelClient(RestClient.builder(httpHosts));

        System.out.println("Started ElasticSearch Client");
    }

    public void stop() throws Exception {
        if (client != null) {
            client.close();
        }
        client = null;
    }
}

设置 ElasticsearchConfig 如下:

ElasticsearchConfig config = new ElasticsearchConfig();
config.setHosts("ip1:port,ip2:port,ip3:port");
