在Elasticsearch中获取TransportClient实例时获取ConnectTransportException

Question

我正在使用TransportClient使用以下代码创建elasticsearch客户实例。

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;
}

问题是代码有时可以正常工作并为数据建立索引，但是有时候我遇到了以下问题。

请帮助我找到问题。

谢谢

您的代码对我来说看起来正确。 如果这是一个间歇性问题，则可以归因于：

• 连线中断

同样按照上一篇文章中的建议，删除与节点相关的设置，然后尝试设置以下提到的属性

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