This topic contains procedures to back up Cloudera Manager. Cloudera
recommends that you perform these backup steps before upgrading. The
backups will allow you to rollback your Cloudera Manager upgrade if
For upgrades from CDH clusters with Cloudera
Navigator to Cloudera Runtime 7.1.1 (or higher) clusters where
Navigator is to be migrated to Apache Atlas, the cluster must have
Kerberos enabled before upgrading.
For upgrades from CDH clusters with Sentry to
Cloudera Runtime 7.1.1 (or higher) clusters where Sentry privileges are
to be transitioned to Apache Ranger, the cluster must have Kerberos
enabled before upgrading.
If the cluster you are upgrading will include Atlas, Ranger, or
both, the upgrade wizard deploys one infrastructure Solr service to
provide a search capability of the audit logs through the Ranger Admin
UI and/or to store and serve Atlas metadata. Cloudera recommends that
you do not use this service for customer workloads to avoid
interference with audit and timeline performance.
