elasticsearch远程客户端到AWS

Question

我一直收到这个错误：

 org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available: []

我的弹性搜索在AWS Ubuntu Linux上。

我的TransportClient包装如下：

@SuppressWarnings("resource")
    public ClientTransport(){


        Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "store_cluster").build();
        this.client = new TransportClient(settings)
        .addTransportAddress(new InetSocketTransportAddress("xx.xx.xx.xx", 9300));
    }

我的考试班：

ClientTransport c = new ClientTransport();
        CreateIndexResponse create = c.client.admin().indices()
                .create(new CreateIndexRequest("logstash-2015.06.04")).actionGet();
        if (!create.isAcknowledged()) {
            System.out.println("failed to create index: " + indexName);
        } else {
            System.out.println("Index created. Index Name: " + indexName);
        }

        c.client.close();

我看到很多关于此的讨论，但我没有得到解决方案？

这是elasticsearch.yml。这些是我文件中唯一的配置：

network.host: localhost
cluster.name: store_cluster
node.name: store_node
