Rohith Sharma K S commented on YARN-8022:
-----------------------------------------
However in secure cluster, unauthorized user will be going into else part since
callerUGI will NOT be null at all. If user is unauthorized then this user will
be blocked in AuthenticationFilter itself. CallerUGI can be null only in
non-secure cluster. So we can proceed ahead with this modification.
