Migrating Navigator audit information into Atlas

Existing Cloudera Navigator audit information is not migrated into the CDP cluster.

To migrate reports running against Navigator data to Apache Ranger and other resources you must review the available options.

To manage Navigator audit information in a CDP Runtime cluster, consider the following options:

Maintain legacy audit information in Navigator

You can continue to run Navigator to access your existing audit information (and/or metadata). If you choose to keep Navigator running, make sure that its users do not add content to the archived system rather than the new Atlas instance. Consider:

  • Removing editing privileges from users. If Navigator is configured for LDAP or Active Directory authentication, you can modify users or groups to remove privileges for adding or editing metadata. For details, see Administering Navigator User Roles.

  • Marking Navigator entities as stale. If you are managing more than one cluster in Navigator, you can mark entities from the upgraded cluster to indicate to users that the entities are no longer maintained in Navigator. One way to do this is to create a policy that assigns a tag to the entities from the upgraded cluster. For details, see Using Policies to Automate Metadata Tagging.

Archive your Navigator audit information

When Cloudera Manager upgrades to 7.x, it maintains the database of Navigator audit information. After the upgrade, you can access audit information through Navigator; new audit information continues to be collected from CDH services.

When you upgrade a CDH cluster to Cloudera Runtime, the Navigator audit information persists. However, services no longer produce audit information for Navigator. You can continue to run Navigator to be able to access the audit information; at some point—perhaps after your need for immediate access to the audit information expires—you can archive the audit information.

At that point, if Cloudera Manager is not managing another CDH cluster, you can shut down Navigator.
