Aaron T. Myers commented on MAPREDUCE-2853:
-------------------------------------------
Patch looks pretty good, Todd. The only thing I notice is that it looks like
there are a few unused imports in the file. +1 pending removal of those.
> Add "teraread" example

> 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)
