Starting Agents

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

Start

sudo service cloudera-scm-agent start

Stop

sudo service cloudera-scm-agent stop

Restart

sudo service cloudera-scm-agent restart

**Hard Stopping and Restarting Agents**

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

Note: The hard_stop and hard_restart commands kill all running managed service processes on the host(s) where the command is run.

1)Hard Stop

For RHEL 7, SLES 12, Debian 8, Ubuntu 16.04:

sudo systemctl stop cloudera-scm-supervisord.service

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

sudo service cloudera-scm-agent hard_stop

2)Hard Restart

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

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

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

sudo service cloudera-scm-agent hard_restart

3)Checking Agent Status

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

Starting/stopping cluster or services (and many other actions) will be done in Cloudera Manager UI or using the Cloudera Manager API

The CM API can be used from curl commands in a shell script or when using the bindings from a Python script or Java code.
