Examples with SniffOnFailureListener org.elasticsearch.client.sniff.SniffOnFailureListener used on opensource projects

Example 1 with SniffOnFailureListener

use of org.elasticsearch.client.sniff.SniffOnFailureListener in project java-apply by javachengwc.

the class EsClientDemo method buildClient7.

public RestClient buildClient7() {
    // 每当出现错误时会立即更新节点列表而不是等待下次更新周期
    SniffOnFailureListener sniffOnFailureListener = new SniffOnFailureListener();
    RestClient restClient = RestClient.builder(new HttpHost("localhost", 9200)).setFailureListener(sniffOnFailureListener).build();
    Sniffer sniffer = Sniffer.builder(restClient).setSniffAfterFailureDelayMillis(30000).build();
    sniffOnFailureListener.setSniffer(sniffer);
    return restClient;
}

Example 2 with SniffOnFailureListener

use of org.elasticsearch.client.sniff.SniffOnFailureListener in project ARLAS-server by gisaia.

the class ElasticTool method getRestHighLevelClient.

public static ImmutablePair<RestHighLevelClient, Sniffer> getRestHighLevelClient(HttpHost[] nodes, boolean ssl, String cred, boolean skipMaster, boolean sniffing) {
    // disable JVM default policies of caching positive hostname resolutions indefinitely
    // because the Elastic load balancer can change IP addresses

        restClientBuilder.setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider));
    }
    RestHighLevelClient client = new RestHighLevelClient(restClientBuilder);
    // Sniffing should be disabled with Elasticsearch Service (cloud)
