Congratulations, you have just executed a job using MapReduce. It was a bit of a boring
task. You could have executed the
grep
command on your Linux machine that runs
much faster than this. However, it gives you a couple of important insights. One, that the
configuration works, and the other is, it is not always the best thing to do everything using
Hadoop; for some tasks, it is better to use the tools that are best suited to them. We will
see more about this when we will discuss the cons of Hadoop later in this chapter.
