Add "teraread" example
----------------------
Key: MAPREDUCE-2853
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2853
Project: Hadoop Map/Reduce
Issue Type: New Feature
Components: benchmarks, examples
Affects Versions: 0.23.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Fix For: 0.23.0
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)
