Starting, Stopping, and Restarting Cloudera Manager Agents

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

• Start

  sudo service cloudera-scm-agent start

To stop or restart Agents while leaving the managed processes running, use one of the following commands:

• Stop

  $ sudo service cloudera-scm-agent stop

• Restart

  $ sudo service cloudera-scm-agent restart

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

• Hard Stop
  • RHEL-compatible 7 and higher:

    $ sudo service cloudera-scm-agent next_stop_hard
    $ sudo service cloudera-scm-agent stop

  • All other Linux distributions:

    $ sudo service cloudera-scm-agent hard_stop
    

• Hard Restart
  • RHEL-compatible 7 and higher:

    $ sudo service cloudera-scm-agent next_stop_hard
    $ sudo service cloudera-scm-agent restart

  • All other Linux distributions:

    $ sudo service cloudera-scm-agent hard_restart
    

  Hard restart is useful for the following situations:
  1. You're upgrading Cloudera Manager and the supervisord code has changed between your current version and the new one. To properly do this upgrade you'll need to restart supervisor too.
  2. supervisord freezes and needs to be restarted.
  3. 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 service cloudera-scm-agent status
