Ambari 1.7.0无法在CentOS集群中注册数据节点
[英]Ambari 1.7.0 cannot register datanodes in CentOS cluster
问题描述
Here is another question about getting hosts to register. 
这是有关使主机注册的另一个问题。 I am using Ambari 1.7.0 on CentOS 6 machines. 我在CentOS 6机器上使用Ambari 1.7.0。 I am trying to install HDP 2.1. 我正在尝试安装HDP 2.1。
First here is the hosts file I am using. 首先是我正在使用的主机文件。 Note each node has the same hosts file: 注意每个节点都有相同的主机文件：
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.144 datanode10.localdomain.com
192.168.200.107 datanode01.localdomain.com
192.168.200.143 namenode.localdomain.com
Also, I can ping each machine for any machine. 另外，我可以对每台计算机执行ping操作。 I can SSH without a password from the name node into the other datanodes. 我可以在没有密码的情况下从名称节点SSH到其他数据节点。 I disabled selinux and iptables on all machines. 我在所有机器上禁用了selinux和iptables。
I am following the startup procedure listed here: https://cwiki.apache.org/confluence/display/AMBARI/Install+Ambari+1.7.0+from+Public+Repositories . 我正在按照此处列出的启动过程进行操作： https : //cwiki.apache.org/confluence/display/AMBARI/Install+Ambari+1.7.0+from+Public+Repositories 。 Please note that these install instructions mention nothing about iptables or selinux. 请注意，这些安装说明未提及iptables或selinux。 People on the mailing list have told me that I need to disable those items. 邮件列表上的人告诉我，我需要禁用这些项目。
Ambari can discover the namenode it is sitting on. Ambari可以发现它所在的名称节点。 It cannot discover the datanodes. 它无法发现数据节点。 I get this error from the registration log file: 我从注册日志文件中收到此错误：

Why is the namenode being appended to the namenode.localdomain.com URL? 为什么将namenode附加到namenode.localdomain.com URL？ Why is the script considering this a valid URL and not throwing an error? 为什么脚本将其视为有效URL而不抛出错误？

What do you have specified as the hostname in /etc/ambari-agent/conf/ambari-agent.ini ? 您在/etc/ambari-agent/conf/ambari-agent.ini中指定了什么主机名？ I assume that it is 'namenode.localdomain.com' 我假设它是“ namenode.localdomain.com”
