> https://archive.epa.gov/robots.txt lists 160k sitemap URLs, absurd! Almost 160k of them are duplicates, no friendly words to describe this astonishing fact.
> And although our Nutch locally chews through this list in 22s, for some weird reason the big job on Hadoop fails, although it is also working on a lot more.
> Maybe this is not a problem, maybe it is. Nevertheless, treating them as Set and not List makes sense.
