> As we know, when Ranger authentication is enabled in the HDFS, if Ranger authentication fails to match, it is degraded to the FSPermissionChecker authentication of the HDFS ACL. 
> If an ACE occurs, it is not clear whether it comes from Ranger authentication or FSPermissionChecker authentication. So I think we should add a description of AccessControlEnforcer to the ACE exception description to help locate the problem.
