Elasticsearch - NoNodeAvailableException

Question

尝试使用Java API for ES 2连接到Elasticsearch 2时出现以下错误.这是代码:

Settings settings = Settings.settingsBuilder().put("cluster.name", Receptor.clusterName).build();
TransportClient transportClient = TransportClient.builder().settings(settings).build();
Client c = null;
try {
     c = transportClient.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(Receptor.es_ip), 9300));
} catch (UnknownHostException e) {
     System.err.println(Util.getTimestampStr() + "UnknownHostException error.");
     e.printStackTrace();
}

CreateIndexRequestBuilder createIndexRequestBuilder = c.admin().indices().prepareCreate(indexName);
createIndexRequestBuilder.addMapping(documentName, json);
createIndexRequestBuilder.execute().actionGet();

我能够在transportClient.connectedNodes()上获取我的ES节点,但是当我尝试添加新的映射时,我得到了NoNodeAvailableException异常.此代码适用于以前版本的Elasticsearch.什么是错的？
