> Current MD5 UDF implementation uses Apache Commons  DigestUtils.md5Hex method to get
md5 hex.
> DigestUtils does not provide md5Hex method with signature (byte[], start, length). This
is why copyBytes method was added to UDFMd5 to get bytes[] from BytesWritable.
> To avoid copying bytes from BytesWritable to new byte array we can use java MessageDigest
API directly.
> MessageDigest has method update(byte[], start, length)
