我已成功安裝Cloudera管理器。它顯示當前託管主機爲127.0.0.1,並處於活動狀態。Cloudera集羣安裝過程中的錯誤?
當我在加載後使用cloudera管理器搜索和安裝集羣時,它顯示以下錯誤。
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).
下圖清楚地顯示了在cloudera管理器上安裝集羣時的問題。
