Ambari 1.7.0無法在CentOS集群中注冊數據節點

Question

這是有關使主機注冊的另一個問題。 我在CentOS 6機器上使用Ambari 1.7.0。 我正在嘗試安裝HDP 2.1。

首先是我正在使用的主機文件。 注意每個節點都有相同的主機文件：

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

另外，我可以對每台計算機執行ping操作。 我可以在沒有密碼的情況下從名稱節點SSH到其他數據節點。 我在所有機器上禁用了selinux和iptables。

我正在按照此處列出的啟動過程進行操作： https : //cwiki.apache.org/confluence/display/AMBARI/Install+Ambari+1.7.0+from+Public+Repositories 。 請注意，這些安裝說明未提及iptables或selinux。 郵件列表上的人告訴我，我需要禁用這些項目。

Ambari可以發現它所在的名稱節點。 它無法發現數據節點。 我從注冊日志文件中收到此錯誤：

為什么將namenode附加到namenode.localdomain.com URL？ 為什么腳本將其視為有效URL而不拋出錯誤？

接下來是完整的注冊日志文件。

您在/etc/ambari-agent/conf/ambari-agent.ini中指定了什么主機名？ 我假設它是“ namenode.localdomain.com”
