It should be noted that no one on the Pig team was involved in setting up
the benchmarks and the queries don't follow the Pig cookbook suggestions for
writing efficient queries, so these results should be considered *extremely*
preliminary. Furthermore, I can't see any way that Hive should be able to
beat raw map/reduce, since Hive uses map/reduce to run the job.

In the future, it would be better to involve the respective communities
(mapreduce-dev and pig-dev) far before pushing benchmark results out to the
user lists. The Hadoop project, which includes all three subprojects, needs
to be a cooperative community that is trying to build the best software we
can. Getting benchmark numbers is good, but are better done in a
collaborative manner.
