Flink service management via ADCM

Konstantin Alpashkin

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

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

Action Description

Add/Remove components

Running this action opens the component-host mapping interface where you can add, remove, and distribute Flink components

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 delete 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
