Pricing depends a lot on how much memory your job requires[1] and how much processing each record requires -- i.e. the pricing is more sensitive to usage. As a very rough estimate, for a light-to-medium load of 1Tb, the cost would probably be in the ballpark of ~$0.50. AWS's own reference MR framework[2] (which is mostly a tech demo) quotes prices in a similar order of magnitude. Corral isn't great for processing-heavy MR jobs, as Lambda pricing rises quickly if you need a lot of memory or take a lot of time with each record. But, for small-ish low-overhead jobs, it can pretty easily beat the pricing and hassle of using something like EMR.
