Core configuration service management via ADCM

Vladimir Adamenkov

The ADCM UI provides actions to manage the Core configuration service and its components. For information on how to run service actions, refer to ADH service actions.

The actions available for the Core configuration service are listed in the table below.

Core configuration service actions
Action	Description
Add/Remove components	Adds/removes the Core configuration component(s). Running this action opens the component-host mapping interface where you can distribute Core configuration components
Export client configurations	Saves to archives all the client configurations (for all the services and for the cluster), without applying them on hosts
Install/Reinstall	Installs or reinstalls the Core configuration service
Update Core configuration	Updates the core-site.xml, hadoop-env.sh, ssl-server.xml, and ssl-client.xml files
Check	Runs service-specific tests to check the health of the service and its components
Start	Starts the service. When you run this action, the option *Apply configs from ADCM* is available. If it is set to `true`, all service configurations defined in ADCM settings will be applied on the service startup. Otherwise, the service starts without applying configurations from ADCM
Stop	Stops the service
Remove	Removes the service from the cluster. This action should be used to remove already installed services. Whereas the control can be used to remove a non-mapped service (a service which components have not been distributed among cluster hosts)
Restart	Restarts the service. When you run this action, the option *Apply configs from ADCM* is available. If it is set to `true`, all service configurations defined in ADCM settings will be applied during the service restart. Otherwise, the service restarts without applying configurations from ADCM
