我尝试使用标准版本在 Ubuntu 12.04.1 LTS 上安装 cloudera 管理器,当我想添加新主机时,出现下一个错误:
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
以下行对于支持 IPv6 的主机是可取的
::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::
[09/Oct/2013 16:04:23 +0000] 4532 MainThread agent ERROR Heartbeating to 192.168.5.xyz:7182 failed.
