Cloudera Rollback Guide Companion
Welcome to the Cloudera Rollback Guide Companion.
You can roll back a failed upgrade to CDP Private Cloud Base 7. The rollback restores your CDH cluster to the state it was in before the upgrade, including Kerberos and TLS/SSL configurations.
This rollback guide companion will help you in achieving the key milestones for successfully completing an in-place rollback of your cluster.
Use the My Environment section to select all of the services in your cluster. Use the Rollback the Cluster tab to access a rollback document that includes only the rollback steps for the services you selected. (Service selection only applies to CDH rollback.)
Getting Started
Rolling back CDP to an earlier version
You can roll back an upgrade from CDP Private Cloud Base 7 to CDH 6. The rollback restores your CDH cluster to the state it was in before the upgrade, including Kerberos and TLS/SSL configurations.
Please review these important notes before beginning a rollback:
- Any data created after the upgrade is lost.
- You must follow all of the steps in the order presented in the Rollback document. Cloudera recommends that you read through the backup and rollback steps before starting the backup process. You may want to create a detailed plan to help you anticipate potential problems.
- These rollback steps depend on complete backups taken before upgrading Cloudera Manager and CDH. Backup steps are included in the linked documents on the Rollback the Cluster tab.
