Overview of Mutual Trust Between Clusters

Function Description

By default, users of a big data cluster in security mode can only access resources in the cluster but cannot perform identity authentication or access resources in other clusters in security mode.

Feature Description

  • Domain

    The secure usage scope of users in each system is called a domain. Each FusionInsight Manager must have a unique domain name. Cross-Manager access allows users to use resources across domains.

  • User Encryption

    Mutual trust can be configured across FusionInsight Managers. The current Kerberos server supports only the aes256-cts-hmac-sha1-96:normal and aes128-cts-hmac-sha1-96:normal encryption types for encrypting cross-domain users, and the encryption types cannot be changed.

  • User Authentication

    After cross-Manager mutual trust is configured, if a user with the same name exists in two systems and the user in the peer system has the permission to access a resource in that system, this user can also access the remote resource.

  • Direct Mutual Trust

    The system saves the mutual trust ticket of the peer system in two clusters with mutual trust configured and uses the mutual trust ticket to access the peer system.
