Description

TestPermission create a user with the following name and group:

 final private static String USER_NAME = "user" + RAN.nextInt();
 final private static String[] GROUP_NAMES = {"group1", "group2"};

   UserGroupInformation userGroupInfo = 
        UserGroupInformation.createUserForTesting(USER_NAME, GROUP_NAMES );
      
      FileSystem userfs = DFSTestUtil.getFileSystemAs(userGroupInfo, conf);

      // make sure mkdir of a existing directory that is not owned by 
      // this user does not throw an exception.
      userfs.mkdirs(CHILD_DIR1);
      

Supposedly

 userfs.setOwner(CHILD_FILE3, "foo", "bar");

will be run as the specified user, but it seems to be run as me who run the test.

Running as the specified user would disallow setOwner, which requires superuser privilege. This is not happening.

Creating this jira for some investigation to understand whether it's indeed an issue.

Thanks.
