background:
Cloudera Manager 6.1.0 added a node to the cluster, and encountered during the installation process: Installation failed. Unable to receive the heartbeat sent by the Agent.
Check the program status by going to the node: systemctl status cloudera-manager-agent found an error: Dependency failed for Cloudera Manager Agent Service.
solve:
1. Log in to the node: use yum to uninstall cloudera-manager-agent and cloudera-manager-daemons
yum remove cloudera-manager-agent
yum remove cloudera-manager-daemons
2. Re-use the Cloudera Manager installation wizard to add the node to the cluster.
Note: Many things on the Internet are caused by turning on Auto-TLS. I did not turn on Auto-TLS, so this is not the reason.
