> In {{JobSubmissionFiles.getStagingDir()}}, we have following code that will
> throw exception if the directory owner is not the current user.
> {code:java}
> String owner = fsStatus.getOwner();
> if (!(owner.equals(currentUser) || owner.equals(realUser))) {
> throw new IOException("The ownership on the staging directory " +
> stagingArea + " is not as expected. " +
> "It is owned by " + owner + ". The directory must " +
> "be owned by the submitter " + currentUser + " or " +
> "by " + realUser);
> }
> {code}
> This check will fail on Windows when the underlying file system is
> LocalFileSystem. Because on Windows, the default file or directory owner
> could be "Administrators" group if the user belongs to "Administrators" group.
> Quite a few MR unit tests that runs MR mini cluster with localFs as
> underlying file system fail because of this.
