Permission Verification Policies

Permission Verification Policies

Security Mode

After a user is authenticated by the Huawei big data platform, the system determines whether to verify the user's permission based on the actual permission management configuration to ensure that the user has limited or all permission on resources. If the user does not have sufficient permission, the user can access resources only after the system administrator grant related permission on each component to the user. The cluster provides permission verification capabilities in both Security Mode and Normal Mode. Permission on components is the same in the two modes.

By default, all components in the cluster in Security Mode perform permission verification on access in a unified manner, and the permission verification function cannot be disabled.

Normal Mode

Different components in the cluster in Normal Mode use different open-source permission verification behavior. Table 7-2 lists detailed permission verification mechanisms.
