我尝试在ubuntu上安装最新的cloudera管理器,当我在psuedo分布式模式下安装cluser时,我得到以下错误,有人可以告诉我该怎么做 我确实尝试了以下内容 a)禁用iptables b)更改了我的etc主机以获得以下条目 127.0.0.1 localhost 127.0.0.1 localhost.localdomain localhost
安装失败。无法从座席接收心跳。
Ensure that the host's hostname is configured properly.
Ensure that port 7182 is accessible on the Cloudera Manager server (check firewall rules).
Ensure that ports 9000 and 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).
答案 0 :(得分:2)
您应该在Cloudera Manager和主机上声明主机名信息。
例如:
在Cloudera经理:
10.1.3.11 hadoop-host1.localdomain hadoop-host1
10.1.3.12 hadoop-host2.localdomain hadoop-host2
...
在每个主持人中:
10.1.3.10 cloudera-manager.localdomain cloudera-manager
简单地说,我为CM和所有主机使用了相同的主机名列表。
