This will also depend on your particular use - since our application is
CPU-bound, it was more economical for us to buy machines with as many cores as
possible. Obviously if you are IO-bound you have different considerations.

If it helps, we're using quad core x86s with anywhere from 4g to 16g of
ram. We've got 4x500g sata drives per box, no raid, swap and root taking a
chunk out of each drive and the rest used for HDFS and/or MR work.
While you can certainly go a much more heterogeneous route than we have,
it should be noted that the more differences in the hardware/software
layout, the more difficult is going to be to maintain them. This is
especially true for large grids where hand-tuning individual machines just
isn't worth the return on effort.

Given the current lack of a security model in Hadoop and the direction
that a smattering of Jira's are heading, "friendly" could go either way:
either not friendly enough or too friendly. :)
