--------------------------------------
Summary: Handle token replacement correctly when token is not
defined in the request context
Key: RANGER-2180
URL: https://issues.apache.org/jira/browse/RANGER-2180
Project: Ranger
Issue Type: Bug
Components: Ranger
Affects Versions: master
Reporter: Abhay Kulkarni
Fix For: master
When a policy resource contains a token (such as \{USER}), and request context
does not have an entry for the token (in this case, USER), then the replacement
fails and the expanded policy resource is set to null. A null policy-resource
will not match any policy, and may cause NPE.
In such case, the original policy resource string should be returned as the
expanded policy resource string.
