Hadoop is much more than MapReduce. It's a fault tolerant, highly scalable file system where you can store a shitload (technical term) of data. That alone is remarkable.

Once your data is there, then you get your map/reduce on. And the best way to get started there is to look into Pig or Hive (high level map/reduce abstractions). Either of those will take you a long way.
