Synchronizing Cluster Configurations

Updated at: Apr 28, 2020 GMT+08:00

Scenarios

If Configuration Status of any service is Expired or Failed, users can synchronize configurations to recover the configuration status.

  • If the configuration status of all services in the cluster is Failed, synchronize the cluster configurations with the background configurations.
  • If the configuration status of some services in the cluster is Failed, synchronize the specified service configurations with the background configurations.

Impact on the System

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

Procedure

  1. On the MRS cluster details page, choose Configure > Synchronize Configuration in the upper right corner.

    Figure 1 Synchronize Configuration

    For MRS 1.8.10 or earlier, follow instructions in Synchronizing Cluster Configurations.

  2. 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 cluster is successfully started.
