Read about MapReduce and Hadoop in Q4 of Chapter 9 if you have not already done so. Is MapReduce suitable for password cracking? Explain your answer. Assume that it is. If it takes 4.5 years for one computer to crack a password, how long will it take 10,000 computers to crack one using Hadoop? If it takes 2 million years to crack a password, how long will it take 10,000 computers to crack one? What does this tell you about password construction?
