我已成功安装 Cloudera 管理器。它将当前管理的主机显示为 127.0.0.1,并且它处于活动状态。
当我在加载后使用 cloudera 管理器搜索和安装集群时,它显示以下错误。
Installation failed. Failed to receive heartbeat from agent.
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).
下图清楚地显示了在 cloudera manager 上安装集群时出现的问题。
