Configuration Rollback
最終更新日:2024-10-30 11:11:43
EMR supports adding, modifying, and deleting configuration items for various service parameters in the console, as well as rolling back configurations. This document introduces how to roll back service parameter configurations through the console.
Directions
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. On the Configuration Management page, select Configuration History. Click Details to view a comparison of parameter values before and after the changes. Click Rollback to recover the parameter configuration changes for that record. Select Rollback > Confirm rollback. After a successful rollback, the service is restarted, and the rollback will take effect shortly.
Description
Adding, modifying, and deleting configuration items support rollback, but adding configuration files and deleting the added configuration files do not support rollback.
