Question

我有一台Windows机器，它在VirtualBox上有一台Ubuntu机器，它运行Elasticsearch 2.4。我通过VirtualBox的端口映射映射了端口9200,9300和5601，并在我的Ubuntu实例中允许iptables上的端口。

但是，当Java尝试连接时，我收到此错误：

org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: [{#transport#-1}{127.0.0.1}{127.0.0.1:9300}]
    at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:290) ~[elasticsearch-2.4.1.jar:2.4.1]

在此错误之前，我也会看到类似的内容，

org.elasticsearch.plugins            : [Chimera] modules [], plugins [], sites []

该日志发生在我最初创建Client对象的代码段的最后一行：

    Settings settings = Settings.builder()
            .put("cluster.name", properties.getClusterName())
            .put("client.transport.sniff", properties.isSniffing())
            .build();
    TransportAddress address;

    try {
        address = new InetSocketTransportAddress(InetAddress.getByName(properties.getHost()), properties.getPort());
    } catch (UnknownHostException exception) {
        logger.error("Error : unknown elasticsearch host " + properties.getHost() + ":"
                + properties.getPort(), exception);

        throw new RuntimeException(exception);
    }

    client = TransportClient.builder().settings(settings).build().addTransportAddress(address);

所以奇怪的是：我最初没有收到错误，但是当我尝试使用同一个客户端插入数据时，我会在以后收到错误。

我在这里使用localhost作为我的主持人。当我尝试0.0.0.0时，我也得到了类似的错误。我可以从浏览器和控制台访问http://localhost:9200。所以我知道端口映射在某种程度上起作用。

有关如何解决此问题的任何帮助表示赞赏。
