It will be very useful to see the hadoop/job config settings and get
some sense of the underlying hardware config.

Subject: Sort benchmark on 2000 nodes

This is FYI. We at Yahoo! could successfully run hadoop (upto date trunk
version) on a cluster of 2000 nodes. The programs we ran were
and Sort. Sort performance was pretty good - we could sort 20TB of data
2.5 hours! Not many task failures - most of those that failed
file checksum errors during merge and map output serving, some got
due to lack of progress reporting. Overall, a pretty successful run.
