【问题描述】：

我正在尝试使用以下 curl 命令添加主机。

curl --user admin:passwd -i -H "X-Requested-By: ambari" -X POST http://182.29.6.3:8080/api/v1/clusters/prod/hosts/ip-182-29-6-3.us-east-2.ec2.internal

但是，我收到了不好的要求

HTTP/1.1 400 错误请求 X-Frame-Options: DENY X-XSS-Protection: 1; 模式=阻止设置 Cookie： AMBARISESSIONID=d52ibb6a8b6q1tmqm2l21q85e;Path=/;HttpOnly 过期： 1970 年 1 月 1 日星期四 00:00:00 GMT 用户：admin 内容类型：text/plain 内容长度：179 服务器：码头（8.1.19.v20160209）

"status" : 400, "message" : "尝试将未知主机添加到 簇。这些主机尚未在服务器上注册： ip-182-29-6-3.us-east-2.ec2.internal"

【参考方案1】：

此命令帮助您通过ambari REST API 将主机添加到hdp 集群，添加YARN 节点管理器服务，在节点上部署配置和启动服务。
