> Improve permission denied message when FSPermissionChecker#checkOwner fails
> ---------------------------------------------------------------------------

> Key: HDFS-6741

> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 3.0.0, 2.5.0

>
> Currently, FSPermissionChecker#checkOwner throws an AccessControlException
> with a simple "Permission denied" message.
> When users try to set an ACL without ownership permissions, they'll see
> something like:
> {code}
> [schu@hdfs-vanilla-1 hadoop]$ hdfs dfs -setfacl -m user:schu:--- /tmp
> setfacl: Permission denied
> {code}
> It'd be helpful if the message had an explanation why the permission was
> denied to avoid confusion for users who aren't familiar with permissions.
