我尝试在 ubuntu 上安装最新的 cloudera 管理器,当我在伪分布式模式下安装 cluser 时出现以下错误,有人可以告诉我该怎么做我已经尝试过以下操作 a) 禁用 iptables b) 将我的 etc 主机更改为有以下条目 127.0.0.1 localhost 127.0.0.1 localhost.localdomain localhost
安装失败。无法从代理接收心跳。
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).
