> After DistCp copies a file, it calls {{getFileStatus}} to get the
> {{FileStatus}} from the destination so that it can compare to the source and
> update metadata if necessary. If the DistCp command was run without the
> option to preserve metadata attributes, then this additional
> {{getFileStatus}} call is wasteful.
