What does it mean by Mahout is built on Hadoop?

I have read that Mahout is developed on Hadoop, and that we can use Mahout with or without Hadoop. What does it mean by saying that Mahout algorithms can be run on Hadoop? Mahout algorithms are not written in Map-Reduce form right?Could you please explain to me with an example?

Thanks!

Solution

  • Did you look at the source code? The algorithms are implemented as Map/Reduce jobs (not all, but much of it), which is exactly why this statement is made.
