> 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.
