---------------------------------
Summary: Improve permission denied message when
FSPermissionChecker#checkOwner fails
Key: HDFS-6741
URL: https://issues.apache.org/jira/browse/HDFS-6741
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 3.0.0, 2.5.0
Reporter: Stephen Chu
Assignee: Stephen Chu
Priority: Minor
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.
