> DistCp uses ThrottleInputStream, which  provides a bandwidth throttling on a 
> specified stream. Currently, Distcp allows the max bandwidth value in Mega 
> Bytes, which does not accept fractional values. It would be better if it 
> accepts the Max Bandwitdh in fractional MegaBytes.
> Due to this we are not able to throttle the bandwidth in KBs in our prod 
> setup.
