Hadoop optimization for Lustre FS
Hello,

there is an optimization for Hadoop on Lustre FS, or any
high-performance distributed filesystem.

The research paper with test results can be found here
http://www.xyratex.com/pdfs/whitepapers/Xyratex_white_paper_MapReduce_1-4.pdf
and a presentation for LUG 2011:
http://www.olcf.ornl.gov/wp-content/events/lug2011/4-12-2011/1100-1130_Nathan_Rutman_MapReduce_Lug_2011.pptx

Basically the optimization is a replacement for http transport in
shuffle phase by simple linking target file to the source one. I
attached a draft patch against hadoop-1.0.0 to illustrate the idea.
How to push this patch upstream?

Thanks,
--
