Overview
Configuration management supports the modification of key configuration parameters for commonly used open-source components such as HIVE and SPARK. You can modify the service configuration for different roles based on actual requirements. This document introduces the directions for configuring parameters through the console.
Note
When you delete custom configuration files in the console’s configuration management, for security reasons, the client will not synchronize the deletion action.
Directions
Editing Configuration
1. Log in to the EMR on TKE Console and click the Cluster ID/Name in the cluster list to enter the cluster details page.
2. On the cluster details page, select Cluster Services, and click the corresponding service to enter the Configuration Management page.
3. After the configuration management page is entered, select the desired role as needed.
4. If you want to search for a specific configuration item or narrow down the search scope, you can use the filter on the left side.
5. Select the configuration file as needed, click Edit Configuration to enter edit mode, and proceed with adding, editing, or deleting configuration items as required.
Select the parameter to be modified and enter the new parameter value. If it is necessary, click Restore to recover to the original value or Default Value to reset to the system-recommended default value.
Some parameters support deletion. To delete the configuration, select Delete > Confirm.
If the desired parameter is not present in the file, you can click Add Configuration Item to open the add configuration item pop-up, and fill in the parameter name and value.
6. After the information is confirmed, click Save Configuration. Once the configuration is successfully applied, click Restart Service to complete the configuration modification.
Description
Note
If modifications are made to the service process configuration, a restart of the service is required after saving for the modifications to take effect.
If modifications are made to the client configuration, the modifications take effect immediately after saving, without restarting the service.
Adding Configuration File
1. Log in to the EMR on TKE Console and click the Cluster ID/Name in the cluster list to enter the cluster details page.
2. On the cluster details page, select Cluster Services, and click the corresponding service to enter the Configuration Management page.
3. If the desired configuration file is not available, click the + (Add Configuration File) on the right to enter the configuration file setup page and fill in the configuration details.
4. After you click Save Configuration, the parameters will be delivered and the configuration file name will be updated in the configuration file list.
5. Custom configuration files, once effective, support modification and deletion operations.
