John Zhuge created HDFS-10378:
---------------------------------
Summary: setOwner throws AccessControlException with wrong message
Key: HDFS-10378
URL: https://issues.apache.org/jira/browse/HDFS-10378
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.8.0
Reporter: John Zhuge
Assignee: John Zhuge
Priority: Minor
Call {{setOwner}} as a non-super user does trigger {{AccessControlException}},
however, the message "Permission denied. user=user1967821757 is not the owner
of inode=child" is wrong. Expect this message: "Non-super user cannot change
owner".
Output of patched unit test {{TestPermission.testFilePermission}}:
