Hard Stop

  If it is not possible to stop all roles immediately, you must do so within 60 days of the hard stop.
2. Run the following command:
  RHEL 7, SLES 12, Debian 8, Ubuntu 16.04 and higher
```
sudo systemctl stop supervisord
```
  RHEL 5 or 6, SLES 11, Debian 6 or 7, Ubuntu 12.04 or 14.04
```
sudo service cloudera-scm-agent hard_stop
```
Hard Restart
1. Stop all roles running on the host. See Stopping All the Roles on a Host.
  If it is not possible to stop all roles immediately, you must do so within 60 days of the hard restart.
2. Run the following command:
  RHEL 7, SLES 12, Debian 8, Ubuntu 16.04 and higher
```
sudo systemctl stop supervisord
sudo systemctl start cloudera-scm-agent
```
  RHEL 5 or 6, SLES 11, Debian 6 or 7, Ubuntu 12.04 or 14.04
```
sudo service cloudera-scm-agent hard_restart
```
Hard restart is useful for the following situations:
1. 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.
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
