Should I download the MapReduce JARs and the Crunch JARs separately?

I downloaded Crunch (the core JAR) and it seems it doesn't come with the MapReduce classes. Do I need to download the MR JARs separately?
If so, which version of MR would match the Hadoop 2 Crunch version?
Thank you!

Yeah, you need to download the Hadoop JARs separately. Crunch is currently
developed against Hadoop 2.5.2, but any version in the Hadoop 2.x.y line
should work.

Best,
Josh
