Bikas Saha commented on HADOOP-8457:
------------------------------------
1) How was JobTracker.java working before this change? Seems to me that it
would not have worked on the local FS for Windows.
{code} if (!systemDirStatus.isOwnedByUser(getMROwner())) {{code}
2) UpgradeUtilities.java - Why does the parent permission need to be set here.
{code}
File parent = new File(parents[i]);
File newDir = new File(parents[i], dirName);
Configuration conf = new Configuration();
createEmptyDirs(new String[] {newDir.toString()});
FileUtil.setPermission(parent, new FsPermission(defaultPermissions));
LocalFileSystem localFS = FileSystem.getLocal(conf);
{code}
3) I am hoping we will be able to replace the "755"s with a some public static
final name.

> 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.
