我已成功安装Cloudera管理器。它显示当前托管主机为127.0.0.1,并处于活动状态。Cloudera集群安装过程中的错误?
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管理器上安装集群时的问题。
