Yongjun Zhang created HDFS-10376:
------------------------------------
Summary: setOwner call is not run as the specified user in
TestPermission
Key: HDFS-10376
URL: https://issues.apache.org/jira/browse/HDFS-10376
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Yongjun Zhang
TestPermission create a user with the following name and group:
{code}
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);
{code}
Supposedly
{code}
userfs.setOwner(CHILD_FILE3, "foo", "bar");
{code}
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.
