弹性搜索节点未加入集群

Question

我创建了具有3个节点，两个主合格节点和一个数据节点的弹性搜索集群， .yml文件配置如下（省略注释的设置）

master_node

问题是不是所有节点都没有创建集群

主节点和数据节点02组成一个集群，数据节点01分别创建一个单独的集群。

.yml配置中是否缺少任何内容？

调用http://(master_node_ip):9200/_cluster/state?pretty

返回

并在data_node_01上调用集群api 返回

任何人都可以帮忙吗？

弹性搜索中的裂脑问题

更新：

您的问题出在discovery.zen.minimum_master_nodes:上 您没有设置该值，默认为1

在您的情况下，符合主控条件的节点为2个，只需要一个节点即可选举主控节点，

master_node和data_node_01将自己分配为主节点 因此裂脑
