	public void setUp() throws Exception {

		Settings esSettings = Settings.builder()
				.put("cluster.name",ElasticSearchConstants.elasticsearch_clusterName)  	//设置ES实例的名称
				.put("client.transport.sniff", true)   //自动嗅探整个集群的状态，把集群中其他ES节点的ip添加到本地的客户端列表中
				.build();

		 * 2. http客户端的方式是以http协议在9200端口上进行通信
