> In dfs, some classes, such as INodeFileUnderConstruction use, StringBytesWritbale as member type.  The values are converted from String to StringBytesWritbale in setter and converted back to String in getter.  These overhead is unnecessary.
> StringBytesWritbale is not used in RPC nor dfs image.  No version change will be introduced.
