-Hadoop optimization for Lustre FS
Alexander Zarochentsev 2012-05-16, 08:34
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
and a presentation for LUG 2011:
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?
