Question

我正在使用TransportClient创建带有以下代码的elasticsearch客户端实例。

public static Client getInstance() {
    String ipAddress = MessageTranslator.getMessage("es.cluster.ip");
    int transportClientPort = Integer.parseInt(MessageTranslator
                .getMessage("es.transportclient.port"));

    logger.debug("got the client ip as :" + ipAddress + " and port :"
            + transportClientPort);
    if (instance == null) {
        logger.debug("the client instance is null, creating a new instance");
        ImmutableSettings.Builder settings = ImmutableSettings
                .settingsBuilder();
        settings.put("node.client", true);
        settings.put("node.data", false);
        settings.put("node.name", "node-client");
        settings.put("cluster.name", "elasticsearch");
        settings.build();
        instance = new TransportClient(settings)
                .addTransportAddress(new InetSocketTransportAddress(
                        ipAddress, transportClientPort));
        logger.debug("returning the new created client instance...");
        return instance;
    }
    logger.debug("returning the existing transport client object connection.");
    return instance;
}

问题有时代码正在工作并索引数据，但有时我遇到了以下问题。

请帮我找到问题。

您的代码对我来说是正确的。如果这是间歇性问题，可以归结为：

连接丢失

同样如上一篇文章所述，删除节点相关设置并尝试设置下面提到的属性

settingsBuilder.put("cluster.name", searchClusterName);
settingsBuilder.put("client.transport.sniff", true);
settingsBuilder.put("http.enabled", "false");

尝试一下并分享您的发现
