【问题描述】：
我们有两个节点的 ElasticSearch2.4.3 集群环境。我想问我应该提供什么 URL 来访问环境，以便它在高可用性下工作？
我们有两个主节点 Node1 和 Node2。 Node1 的主机名是 node1.elastic.com，Node2 是 node2.elastic.com。根据公式（n/2 +1），两个节点都是master。
我们通过修改 elastic.yml 文件来启用集群设置 discovery.zen.ping.unicast.hosts 用于两个节点。
从我们的 java 应用程序中，我们连接到 node1.elastic.com。在两个节点都启动之前它工作正常。数据正在两个 ES 服务器中填充，一切都很好。但是一旦 Node1 出现故障，整个弹性搜索集群就会断开连接。而且它不会自动切换到Node2来处理请求。
我觉得我给的网址不对，必须是别的东西才能提供自动切换。
