> 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.
