Review Comment:
It sets the owner and group when you add permissions right

> Manifest distcp often creates large file directory structures when copying
> files from one location to another. There is a risk when concurrently
> publishing files from a directory structure where the folders may not exist
> before renaming files, described by the javadoc:
> {code:java}
> * Renames a src {@link Path} on fs {@link FileSystem} to a dst {@link Path}.
> If fs is a {@link LocalFileSystem} and
> * src is a directory then {@link File#renameTo} is called directly to avoid a
> directory rename race condition where
> * {@link org.apache.hadoop.fs.RawLocalFileSystem#rename} copies the
> conflicting src directory into dst resulting in
> * an extra nested level, such as /root/a/b/c/e/e where e is repeated. {code}
> Given that on HDFS it does not use a RawLocalFileSystem in many
> implementations, we want to pre-create the folders copied sequentially to
> safely create the folders before publishing the files.
