Question

Settings settings = Settings.settingsBuilder()
                .put("cluster.name", "logging_elasticsearch")
                .build();
        TransportClient client = TransportClient.builder()
                .settings(settings)
                .build()
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByAddress(new byte[]{10,100,30,62}), 9300));

  SearchResponse response = client.prepareSearch("logstash-2016.09.08")
            .setTypes("type1", "type2")
            .setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
            .setQuery(QueryBuilders.termQuery("multi", "test"))                 // Query
            .setPostFilter(QueryBuilders.rangeQuery("age").from(12).to(18))     // Filter
            .setFrom(0).setSize(60).setExplain(true)
            .execute()
            .actionGet();

elasticsearch.yml 我在执行搜索查询时收到NoNodeAvailableException。

我试过这个解决方案： https://stackoverflow.com/a/33875764/2616923 但它不起作用。

Answer 1

尝试这种方式，您的代码似乎非常接近：

Settings settings = Settings.settingsBuilder()
        .put("cluster.name", "<elasticsearch-cluster-name>")
        .build();

Client client = new TransportClient.Builder()
            .settings(settings)
            .build()
            .addTransportAddress(new InetSocketTransportAddress(new InetSocketAddress("<elasticsearch-network-host>", <elasticsearch-transport-client-port|default 9300>)));

==== elasticsearch.yml ====

cluster.name: <elasticsearch-cluster-name>
node.name: <elasticsearch-network-host>
network.host: <elasticsearch-network-host>
network.bind_host: 0

尝试使用如下节点名称设置设置

Settings esSettings = Settings.builder().put("cluster.name", esClusterName)
.put("node.name",esNodeName)

Answer 3

I have created transport client with more parameters. Below code is perfectly running in production.

   Settings settingsBuilder = Settings.builder()
            .put("cluster.name", DBPropertyUtil.getPropertyByName("es.cluster")).put("client.transport.sniff", true).put("client.transport.ignore_cluster_name", true).build();

       Client client = new PreBuiltTransportClient(settingsBuilder)
            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(host), port));

Put respective details for host, port, clusterName as per your elasticSearch Servers config.

如果在全新安装Java和ElasticSearch的服务器上遇到此错误，请检查是否存在JAVA_HOME环境设置并将其设置为JRE的正确路径。例如：

JAVA_HOME = C：\ Program Files \ Java \ jre1.8.0_192

Elasticsearch NoNodeAvailableException没有配置的节点可用
