ElasticSearch java客户端更新时出现的错误:NoNodeAvailableException[None of the configured nodes are available

下午尝试 用ElasticSearch  的java客户端去做数据检索工作,测试了一下批量更新,代码如下:

public static void bulkUpdateGoods(List<Goods> goods) throws IOException, InterruptedException, ExecutionException {
Client client = null;
try {
client = TransportClient.builder().build()
.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("hadoop-slave4"), 9300)); } catch (Exception e) {
e.printStackTrace();
} BulkRequestBuilder req = client.prepareBulk(); for (Goods good : goods) {
req.add(client.prepareIndex("smms", "goods", good.getId() + "")
.setSource(jsonBuilder().startObject().field("unit", good.getUnit()).field("price", good.getPrice())
.field("name", good.getName()).field("barcode", good.getBarCode()).endObject()));
} BulkResponse res = req.execute().actionGet(); if (res.hasFailures()) {
System.out.println("Error");
} else {
System.out.println("Done");
} client.close();
}
}

但是测试的时候老是给我报这个错误:NoNodeAvailableException[None of the configured nodes are available。具体没截图。

然后我改正两点后解决问题,一处是用9300端口 而不是9200.9200端口只是HTTP端口。

第二处是我把配置文件里cluter.name给注释掉了,就能用了。具体原理不清楚。
