If you are running out of interesting projects to experiment with during this seasonal break, Parkour is a Clojure library for writing MapReduce jobs.
Parkour is our new Clojure library that carries this philosophy to the Apache Hadoop’s MapReduce platform. Instead of hiding the underlying MapReduce model behind new framework abstractions, Parkour exposes that model with a clear, direct interface. Everything possible in raw Java MapReduce is possible with Parkour, but usually with a fraction of the code.
