             Summary: Refactor policy engine
                 Key: RANGER-2652
                 URL: https://issues.apache.org/jira/browse/RANGER-2652
             Project: Ranger
          Issue Type: Improvement
          Components: Ranger
    Affects Versions: master
            Reporter: Abhay Kulkarni
            Assignee: Abhay Kulkarni
             Fix For: master, 2.1.0


Objectives are:
 # Encapsulate Ranger policy evaluators into a class (PolicyEngine)
 # Separate Ranger Policy Engine APIs based on their users (plugin or ranger-admin), and define corresponding wrapper interfaces (RangerPolicyEngine and RangerServicePoliciesAdmin). Provide their respective implementation classes.
 # Remove unused functionality (keeping usage-counts, re-ordering policy-evaluators based on their usage, etc.)
 # Separate out request preprocessing into a separate interface (RangerAccessRequestProcessor) which wraps context-enrichers and roles for pre-processing/enriching access request.
 # Optimize Trie for incremental changes (adds/deletes)
 # Assorted code clean-up.
