Starting, Stopping, and Restarting Cloudera Manager Agents

Starting Agents

To start Agents, the supervisord process, and all managed service processes, use the following command:
  • Start
    sudo systemctl start cloudera-scm-agent

Stopping and Restarting Agents

To stop or restart Agents while leaving the managed processes running, use one of the following commands:
  • Stop
    sudo systemctl stop cloudera-scm-agent
  • Restart
    sudo systemctl restart cloudera-scm-agent

Hard Stopping and Restarting Agents

To stop or restart Agents, the supervisord process, and all managed service processes, use one of the following commands:
  • Hard Stop
    RHEL 7, RHEL 8, SLES 12, Ubuntu 18.04, Ubuntu 20.04 and later versions
    sudo systemctl stop cloudera-scm-supervisord.service
sudo systemctl stop cloudera-scm-agent
  • Hard Restart
    RHEL 7, RHEL 8, SLES 12, Ubuntu 18.04, Ubuntu 20.04 and later versions
    sudo systemctl stop cloudera-scm-supervisord.service
sudo systemctl restart cloudera-scm-agent
    Hard restart is useful for the following situations:
    • You are upgrading Cloudera Manager and the supervisord code has changed between your current version and the new one. To properly do this upgrade you need to restart supervisor too.
    • supervisord freezes and needs to be restarted.
    • You want to clear out all running state pertaining to Cloudera Manager and managed services.

Checking Agent Status

To check the status of the Agent process, use the command:
sudo systemctl status cloudera-scm-agent
