> These are the examples/benchmark programs that I've been using to test Hadoop map/reduce
with. The first is a program that runs 10 maps/node and each map writes 1 gig of random data
to a dfs file as a SequenceFile of BytesWritable/BytesWritable.
> The second uses the identity map and reduce to sort the data and write it out to dfs.
