Starting, Stopping, and Restarting Cloudera Manager Agents

To start Agents, the supervisord process, and all managed service processes, use the following command:

• Start

  sudo systemctl start cloudera-scm-agent
  

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
  

To stop or restart Agents, the supervisord process, and all managed service processes, use one of the following commands:

• Hard Stop

  RHEL 7, SLES 12, Ubuntu 16.04

  sudo systemctl stop cloudera-scm-supervisord.service
  

  RHEL 5 or 6, SLES 11, Debian 6 or 7, Ubuntu 12.04, 14.04

  sudo systemctl stop cloudera-scm-agent
  

• Hard Restart

  RHEL 7, SLES 12, Debian 8, Ubuntu 16.04 and higher

  sudo systemctl stop cloudera-scm-supervisord.service
  sudo systemctl restart cloudera-scm-agent
  

  RHEL 5 or 6, SLES 11, Debian 6 or 7, Ubuntu 12.04, 14.04

  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.

To check the status of the Agent process, use the command:

sudo systemctl status cloudera-scm-agent
