Synchronizing Service Configurations

Scenario

If Configuration Status of any service is Expired or Failed, users can synchronize configurations for the cluster or service to recover its configuration status. If the configuration status of all services in the cluster is Failed, synchronize the cluster configurations with the background configurations.

Impact on the System

After synchronizing service configuration, users need to restart the service that had an expired configuration. The service is unavailable during the restart.

Procedure

  1. On MRS Manager, click Service.
  2. Select the target service from the service list.
  3. Click More in the upper pane, and select Synchronize Configuration from the drop-down list.
  4. In the dialog box that is displayed, select Restart services or instances whose configurations have expired, and click OK.

    When Operation succeeded is displayed, click Finish. The service is started successfully.
