Question

我是ES的新手。我想在elasticsearch.yml文件中为同一个集群添加一些新节点，但是当我尝试检查集群运行状况时出现此错误

(GET _cluster/health):
   "error": "MasterNotDiscoveredException[waited for [30s]]",
   "status": 503

这是我的配置文件：

cluster.name: mycluster6
node.name: "nodeA"
node.master: true
node.data: true
discovery.zen.ping.multicast.enabled: false

cluster.name: mycluster6
node.name: "nodeB"
node.master: false
node.data: true
discovery.zen.ping.multicast.enabled: false

cluster.name: mycluster6
node.name: "nodeC"
node.master: false
node.data: true
discovery.zen.ping.multicast.enabled: false

cluster.name: mycluster6
node.name: "nodeD"
node.master: false
node.data: true
discovery.zen.ping.multicast.enabled: false

discovery.zen.minimum_master_nodes: 3

在控制台中：
