【问题标题】：How to add host into the ambari-server cluster?如何将主机添加到 ambari-server 集群中？
【发布时间】：2018-10-29 18:30:51
【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;

【解决方案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。
