Ivan Mitic commented on HADOOP-8457:
------------------------------------
DiskChecker.java/SecureIOUtils.java: Enabling Hadoop permission checks on
Windows.
FileStatus.java/RawLocalFileSystem.java: By default, Windows Server 2003+ sets
Administrators group as owner of newly created files/folders if the current
user was a member of the Admin group. Please take a look at
http://support.microsoft.com/kb/318825 for more information. Given that some
places in Hadoop code assert that whoever created the file must be the owner,
making appropriate code changes to account for this platform difference. In the
current model, the user ownership check is abstracted away to allow us to
handle this OS specific behavior.
JobTracker.java/JobSumitssionFiles.java: No need to explicitly set the
ownership anymore (undoing the prior change).
MiniDFSCluster.java/UpgrateUtilities.java: Default permissions on Windows are
"700" while the code expects them to be "755". Changing test code to not have
expectations on default local FS permissions, but to set the corresponding
permissions explicitly.
TestDFSShell.java: Enabling previously disabled test on Windows.
This Jira is also dependent on the fix for HADOOP-6527, otherwise, a test that
creates a test user will remove all group mappings for the real user and cause
all subsequent checks for Admin group membership to fail. Patch for HADOOP-6527
is also available.

> On Linux, the initial file owners are the creators. (I think this is true in
> general. If there are exceptions, please let me know.) On Windows, the file
> created by a user in the Administrators group has the initial owner
> ‘Administrators’, i.e. the the Administrators group is the initial owner of
> the file. As a result, this leads to an exception when we check file
> ownership in SecureIOUtils .checkStat() method. As a result, this method is
> disabled right now. We need to address this problem and enable the method on
> Windows.
