Description

In HDFS-1314, it made the dfs.blocksize can accept different size type like mb, kb, gb, etc. Using "dfs.block.size=8388608" works and "dfs.block.size=8mb" also can work, and this type will finally transform to byte format. So we also can make similar property dfs.datanode.balance.bandwidthPerSec be friendly accepted in size unit.
