Deleting an MRS Cluster

To delete or unsubscribe from a cluster, wait until data analysis and storage are finished, or if the cluster is not functioning properly and cannot provide services. If an MRS cluster fails to be deployed, the cluster is automatically deleted or unsubscribed.

  • You can delete a pay-per-use cluster if you no longer need it after completing a job. The deleted or unsubscribed cluster is no longer billed.
  • You cannot delete a cluster that is billed yearly/monthly if you no longer need it after completing a job. You can unsubscribe from this cluster.

    After a cluster is unsubscribed, resources and data will be deleted and cannot be restored. Ensure that the data is backed up before unsubscribing from the cluster. For details about the unsubscription rules, see Conditional Unsubscription.

After deleting a component or cluster connected to OBS (including scenarios with storage and compute decoupled or where hot and cold datasets are stored separately), you must manually delete the service data on OBS.

Deleting an MRS Pay-per-Use Cluster

  1. Log in to the MRS management console.
  2. In the navigation pane on the left, choose Active Clusters.
  3. In the cluster list, locate the row containing the cluster to be deleted, and click Delete in the Operation column. In the Delete Cluster dialog box, enter DELETE in the confirmation text box and click OK.

    The cluster status changes from Running to Deleting, and finally to Deleted. You can view the deleted cluster in Cluster History. The deleted cluster is no longer billed.

Unsubscribing from a Yearly/Monthly MRS Cluster

  1. Log in to the MRS management console.
  2. In the navigation pane on the left, choose Active Clusters.
  3. In the Operation column of the cluster from which you want to unsubscribe, click Unsubscribe.
  4. On the Unsubscribe page, confirm the cluster information, select reasons for unsubscription, and confirm the unsubscription amount and related fees.
  5. Click Confirm.
  6. Confirm the unsubscription information and click Yes to submit the unsubscription application.

    After the unsubscription application is submitted, the cluster status changes from Running to Deleting. After the cluster is deleted, the cluster status changes to Deleted and is displayed in Cluster History.
