Question

我正在尝试创建用于集成测试的嵌入式ElasticSearch节点。

以下是代码创建

private static final String THREAD_NAME = "ES-THREAD";
private static final String CLUSTER_NAME = "ES-INTEGRATION-TEST";
private static final String ES_HOME_PATH = "elastic-search-home";
private static final String ES_DATA_PATH = "elastic-search-data";
private static final String DATA_PORTS = "9500-9599";
private static final String TRANSPORT_PORTS = "9600-9699";
public void before() throws Throwable {
        try {
            homeDir = Files.createTempDirectory(ES_HOME_PATH);
            dataDir = Files.createTempDirectory(ES_DATA_PATH);

            log.info("Created temp directory {} and {}", homeDir, dataDir);
        } catch (IOException ex) {
            throw new IllegalStateException("Temp Elastic Search directory not created", ex);
        }

        Properties props = new Properties();

        props.setProperty("name", THREAD_NAME);
        props.setProperty("path.home", homeDir.toString());
        props.setProperty("path.data", dataDir.toString());
        props.setProperty("http.port", DATA_PORTS);
        props.setProperty("transport.tcp.port", TRANSPORT_PORTS);
        props.setProperty("node.local", "true");
        props.setProperty("script.groovy.sandbox.enabled", "true");
        props.setProperty("script.engine.groovy.inline.aggs", "true");
        props.setProperty("script.engine.groovy.inline.search", "true");
        props.setProperty("script.engine.groovy.inline.update", "true");
        props.setProperty("script.engine.groovy.inline.mapping", "true");


        esNode = NodeBuilder.nodeBuilder().local(false).client(false)
                .settings(Settings.settingsBuilder().put(props).build()).clusterName(CLUSTER_NAME).build();

        esNode.start();
}

在测试的代码中，有以下方法创建到ElasticSearch的传输连接

private Client createClient() throws UnknownHostException {
    Settings.Builder builder = Settings.builder();
    builder.put("cluster.name", clusterName);
    builder.put("client.transport.ignore_cluster_name", true);

    Settings settings = builder.build();
    return TransportClient.builder().settings(settings).build()
            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(hostname), port));
}

当我进行测试时，我收到了例外情况

我为测试代码发送的主机名值是localhost，我通过

发送我从嵌入式ElasticSearch中提取的端口

NodeInfo nodeInfo = esNode.client().admin().cluster().prepareNodesInfo(localNodeId).get().iterator().next();
transportAddress = nodeInfo.getTransport().address().publishAddress().getAddress();

我看到传输端口始终为0，当我评估nodeInfo.getTransport（）。address（）时，它的值是local [1]。

节点创建中的错误是什么？我需要添加其他配置吗？

谢谢，

当我改变props.setProperty（＆＃34; node.local＆＃34;，＆＃34; true＆＃34;）; to props.setProperty（＆＃34; node.local＆＃34;，＆＃34; false＆＃34;）;传输端口已创建。

嵌入式ElasticSearch无法在集成测试中连接到传输端口
