Description

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.
