             Summary: Deny & allow/deny exceptions in policies should be optional
                 Key: RANGER-874
                 URL: https://issues.apache.org/jira/browse/RANGER-874
             Project: Ranger
          Issue Type: Sub-task
          Components: admin
    Affects Versions: 0.6.0
            Reporter: Madhan Neethiraj
            Assignee: Madhan Neethiraj


Ranger policy model in 0.5 release and earlier supported the ability to specify the conditions (user/group/ip/custom-condtions) to allow an access to a resource. The policy model has been updated for the next release (0.6), with ability to specify conditions to deny an access to a resource; in addition the model.

To support this update, Ranger Policy UI has been enhanced to show policy-items in 4 groups: allow, allow-exceptions, deny and deny-exceptions. Comments earlier in RANGER-606 suggested that introduction of deny and exceptions adds complexity. To address this concern, the enhancements will be made optional via servicedef. Only servicedefs that opt-in (for deny and exceptions in policies) will be able to use these enhancements. For servicedefs that don't opt-in, Ranger Admin will not show deny and exception policy-item groups; also the policy-engine will ignore dent and exception policy-items if found in policies - there by maintaining the simplicity of the current policy model.
