-----------------------------------
Summary: Add an implementation class that prints
AccessControlEnforcer when an ACE exception occurs.
Key: HDFS-17447
URL: https://issues.apache.org/jira/browse/HDFS-17447
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs
Reporter: xiaojunxiang
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.
