主要问题出现在最后两行。
上网查找原因,，可能的原因有：

1，地址：http://stackoverflow.com/questions/27531215/ambari-1-7-0-cannot-register-datanodes-in-centos-cluster

说明：查看/etc/ambari-agent/conf/ambari-agent.ini文件，看hostname是否改成本机的主机名；

即，改成对应的master，slave1，slave2；

2，地址：http://superuser.com/questions/825443/registration-with-the-server-failed-while-configuring-amabri-on-centos-7

说明：CentOS版本问题，使用CentOS7的话会失败，使用CentOS6,5成功；

3，地址：http://stackoverflow.com/questions/38423925/ambari-confirm-hosts-step-fails-registration-with-the-server-failed

说明：中文和英文操作系统版本问题，中文操作系统出错，英文则成功；

Hey,thank both of you.i got it.The character in China is UTF8,and Ambari is ascii.And Python 2.6 for UTF8 has a bug.

和

I think this is because I set a non-English language (i.e,. Trad. Chinese) as a default language when I installed CentOs 7. It would encounter a charset problem (UTF-8<->ascii) when confirming hosts. After changing the default language to English, This problem has been solved.

解决方法是将系统的默认语言改成英语。
