Scenarios
After creating an Elastic MapReduce (EMR) Serverless TCBase instance, you can perform operations such as modifying instance configurations, scaling out storage, modifying tags, and changing the instance display name.
Operation Steps
Modifying Instance Configurations
Note:
The instance will be shut down during the configuration change process, which may affect normal instance usage or even cause business interruption. Please evaluate carefully before proceeding.
The instance will restart by default after the configuration change. Please perform this operation during off-peak business hours.
Prerequisites
1. After configuration adjustments, pay-as-you-go nodes will have their fees re-frozen based on the latest unit prices. For yearly/monthly subscription clusters, the corresponding fee difference must be covered. Please ensure that your account balance is sufficient.
2. The refund amount will be returned to your Tencent Cloud account in proportion to the cash and gift credits used at the time of purchase. Discounts or vouchers used during the purchase will not be refunded.
Operation Steps
1. Log in to the EMR Serverless TCBase console, find the instance that needs to be modified from the instance list, and click the instance ID to go to the instance information page. 2. In the Instance Information > Deployment Information module, click Change Configuration.
3. On the Adjust Configuration page, confirm the relevant configuration adjustments, select the target instance specifications, carefully read the important notes, and check the box to agree to the changes.
4. Click Confirm to apply the changes.
Scaling Out Storage
1. Log in to the EMR Serverless TCBase console, find the instance that needs to be modified from the instance list, and click the instance ID to go to the instance information page. 2. In the Instance Information > Deployment Information module, click Scale-out Storage.
3. After the storage scale-out operation panel opens, adjust the target storage as needed.
4. Click Confirm to apply the changes.
Modifying Tags
1. Log in to the EMR Serverless TCBase console, find the instance that needs to be modified from the instance list, and click the instance ID to go to the instance information page. 2. In the Instance Information > Basic Information module, click Edit next to the tag information.
3. After the tag editing operation panel opens, add new tags or remove old tags for the instance as needed.
4. Click Confirm to apply the changes.
Changing the Instance Display Name
2. Move the mouse pointer over the name of the instance to be modified, and click Edit.
3. After the instance name modification panel opens, enter the new instance name.
4. Click Confirm to save the changes.
