Ivan Mitic commented on HADOOP-8457:
------------------------------------
Thanks for the feedback!
1. Previously, we were setting the ownership explicitly (this is no longer
needed and is backed out).
2. Good catch. Both parent and child permissions are later cheched by product
code, so the test has to set the permissions accordingly.
3. There is one indeed, {{DataNode.DEFAULT_DATA_DIR_PERMISSION}}, but currently
it is private. I'll make it public and re-use. Make sense?

> 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.
