我选择使用Cloudera Manager通过自动安装程序安装CDH，下载完成但由于此错误无法推送：
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 not in use 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).
If Use TLS Encryption for Agents is enabled in Cloudera Manager (Administration -> Settings -> Security), ensure that /etc/cloudera-scm-agent/config.ini has use_tls=1 on the host being added. Restart the corresponding agent and click the Retry link here.
但是，在查看详细信息后，我在此错误详细信息中看到无法连接到上一个主管：
Installation script completed successfully.
