我正在尝试使用两个节点设置 Elastic Search 集群，但我一直收到此错误。

[o.e.d.z.ZenDiscovery     ] [master-node] not enough master nodes discovered ?during pinging (found [[Candidate{node={master-node}{EzeNCWZBR0aAKUP6Va9ZwA}{ZFq4O019Q2WVEWiISBQi2g}{ip-172-31-6-165}{172.31.6.165:9300}{ml.machine_memory=8369979392, xpack.installed=true, ml.max_open_jobs=20, 
ml.enabled=true}, clusterStateVersion=-1}]], but needed [2]), pinging again

这是我的节点配置：

1. Master Node
    cluster.name: prod-analytic-stats
     node.name: master-node
     path.data: /var/lib/elasticsearch
     path.logs: /var/log/elasticsearch
     network.host: ip-172-31-6-165
     discovery.zen.ping.unicast.hosts: ["ip-172-31-21-37", "ip-172-31-6-165"]
     discovery.zen.minimum_master_nodes: 2



2. data node
     cluster.name: prod-analytic-stats
     node.name: replica-node
     path.data: /var/lib/elasticsearch
     path.logs: /var/log/elasticsearch
     network.host: ip-172-31-21-37
     discovery.zen.ping.unicast.hosts: ["ip-172-31-21-37", "ip-172-31-6-165"]
     discovery.zen.minimum_master_nodes: 1

但是我可以从主节点 ping 数据节点。

root@ip-172-31-6-165:/etc/elasticsearch# ping 172.31.21.37
