---------------------------------
Summary: Logging the username when deny the setOwner operation
Key: HDFS-10455
URL: https://issues.apache.org/jira/browse/HDFS-10455
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.7.2
Reporter: Tianyin Xu
Priority: Minor
Attachments: HDFS-10455.000.patch
The attached patch appends the user name in the logging when the setOwner
operation is denied due to insufficient permissions on this user (based on
his/her name).
The same practice is used in {{FSPermissionChecker}} such as {{checkOwner()}}
and {{checkSuperuserPrivilege()}}.

if (!pc.isSuperUser()) {
if (username != null && !pc.getUser().equals(username)) {
- throw new AccessControlException("Non-super user cannot change
owner");
+ throw new AccessControlException("User " + pc.getUser()
+ + " is not a super user (non-super user cannot change owner).");
}
if (group != null && !pc.containsGroup(group)) {
- throw new AccessControlException("User does not belong to " + group);
+ throw new AccessControlException("User " + pc.getUser()
+ + " does not belong to " + group);
}
{code}
