> Currently, external tables replication, copies the data in directory level.
> So, if target directory exist, then DistCp should compare and update or skip
> data files in the directory instead of creating new directory inside
> pre-existing target directory.
> This can be achieved using -update.
> Also, -delete option is needed to delete the files missing in source
> directory but present in target.
> Hive should mandate these DistCp options even if user passes other options.
