Doug Cutting commented on HADOOP-2233:
--------------------------------------
> I think this patch needs to be in a src/benchmarks directory
We currently put benchmarks in the src/test tree, which doesn't seem bad.
Benchmarks are a kind of test. And, so long as the class name does not start
with "Test" then they're not picked up by JUnit. I don't see a big need for a
separate tree for benchmarks.

> This matches the hadoop.sort.(map|reduce).keep.percent interface in
> HADOOP-2127 and includes an "indirect" sort matching some user apps (when
> locality information is unavailable). It mostly, merely merges parts of the
> RandomWriter and Sort examples to effect sample loads in map/reduce.
