Description

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.
