hadoop – Cloudera Manager安装无法从代理接收心跳 – 将新主机添加到群集

2023年7月4日 384次阅读

我尝试使用标准版在Ubuntu 12.04.1 LTS上安装cloudera管理器,当我想添加新主机时,我得到下一个错误：

Installation failed.Failed to receive heartbeat from agent.
Ensure that the host's hostname is configured properly.
Ensure that port 7182 is accesible on the Cloudera Manager server (check firewall rules).
Ensure that ports 9000 an 9001 are free on the host being added.
Check agent logs in /var/log/cloudera-scm-agent/ on the host being added (some of the logs can be found in the installation details).

在/ etc / hosts文件中,我将其配置为：

127.0.0.1 localhost
127.0.0.1 hadoop-ubuntu
192.168.5.xyz hadoop-ubuntu.dana.local hadoop-ubuntu
192.168.3.xyz ro-m81.dana.local ro-m81
192.168.3.abc ro-m41.dana.local ro-m41

对于支持IPv6的主机,以下行是理想的

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters     
The **/var/log/cloudera-scm-agent/cloudera-scm-agent.log** shows the next error::

请帮助我找到为什么我收到此错误或我错过了什么.

最佳答案 我遇到过同样的问题.这就是我的诀窍.

输入ifconfig并找到你的IP地址.不是127.0.0.1.

键入$hostname并找到您的主机名

编辑/ etc / hosts文件

在那边为你的ipaddress添加一个条目.就像是

192.168.8.xxx   hostname.test.com   hostname

重启cloudera服务.转到sonic.test.com:7180然后再试一次.
它应该工作.即使没有工作,请转到http://hostname.test.com:7180/cmf/home检查主机的状态.

事实证明,即使我收到心跳错误,主机实际上已启动并运行.
