MapReduce: All content tagged as MapReduce in NoSQL databases and polyglot persistence
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.

Shaun Connolly (Hortonworks) lists the 3 most commons usages of Hadoop in a guest post on GigaOm:
- Data refinery
- Data exploration
- Application enrichment
Nothing new here, except the new buzzwords used to describe those Hadoop use cases that were slowly, but steadily establishing as patterns. And even if they sound nicer than ETL, analytics, etc. I doubt anyone needed new terms.
