我试图将协调器节点添加到群集中，但是运行它时却遇到此错误：
@Html.DisplayFor主节点中的错误是：
[2020-09-22T14:03:00,808][INFO ][o.e.c.c.JoinHelper ] [coordinator-node] failed to join {MASTER-02}{7ZSdp7FQQaa_34eM2LQzjA}{-HOAFDSlSF-iDOnE4ZSdFg}{10.13.81.12}{10.13.81.12:9300}{dilmrt}{ml.machine_memory=8365060096, ml.max_open_jobs=20, xpack.installed=true, data=hot, transform.node=true} with JoinRequest{sourceNode={coordinator-node}{Wb5iaDUWS5qKmiO7P9ABEg}{KvuU9jjPROCcCFdHyvon1g}{10.13.81.40}{10.13.81.40:9300}{xpack.installed=true, transform.node=false}, minimumTerm=74, optionalJoin=Optional[Join{term=74, lastAcceptedTerm=0, lastAcceptedVersion=0, sourceNode={coordinator-node}{Wb5iaDUWS5qKmiO7P9ABEg}{KvuU9jjPROCcCFdHyvon1g}{10.13.81.40}{10.13.81.40:9300}{xpack.installed=true, transform.node=false}, targetNode={MASTER-02}{7ZSdp7FQQaa_34eM2LQzjA}{-HOAFDSlSF-iDOnE4ZSdFg}{10.13.81.12}{10.13.81.12:9300}{dilmrt}{ml.machine_memory=8365060096, ml.max_open_jobs=20, xpack.installed=true, data=hot, transform.node=true}}]}
协调器节点的配置为：
[2020-09-22T14:00:14,731][WARN ][o.e.c.c.Coordinator ] [MASTER-02] failed to validate incoming join request from node [{coordinator-node}{Wb5iaDUWS5qKmiO7P9ABEg}{KvuU9jjPROCcCFdHyvon1g}{10.13.81.40}{10.13.81.40:9300}{xpack.installed=true, transform.node=false}]
org.elasticsearch.transport.RemoteTransportException: [coordinator-node][10.13.81.40:9300][internal:cluster/coordination/join/validate]
有人可以告诉我哪里是错误！ 感谢您的帮助：）
