> Teragen is a good benchmark of raw DFS write throughput. Terasort is a good
> benchmark of the whole MR system (input, shuffle, output). I've added a
> simple "teraread" example which reads through the terasort input data without
> performing any processing: this acts as a good benchmark of a read-only
> workload (similar to real-life "find a needle in a haystack" MR jobs)
