Hmm... ok. You actually _may_ have e
Arun,
Thanks a lot for your response.
I am running on a 16 core Xeon processor and 12 spindles.So running 12
Mappers with 2G and 6 Reducers with 3G might give me the best
performance.Also is there a general formula to arrive at those numbers?

Pavan,
A very important factor is how much CPU and how many spindles you have...
Your proposal for memory (44G in all) seems reasonable.
However, if you have 12 spindles and sufficient CPU I'd do something like 10 or
12 maps of 2G each and 6 reduces with 3G/4G each depending on how you want to
