      Description

      A single DistCp command may potentially copies a huge number of files/bytes. In such case, DistCp will run a long time and there is no way stop it nicely. It would be good if DistCp have an option to limit the number of files/bytes being copied. Once the limit is reached, DistCp will terminate and return success. All files copied are guaranteed to be good and there is no partially copied file.
