Subject [jira] [Commented] (NUTCH-2730) SitemapProcessor to treat sitemap URLs as Set instead of List
Date Tue, 20 Aug 2019 20:03:00 GMT

Markus Jelsma commented on NUTCH-2730:
--------------------------------------

Hello [~wastl-nagel]!

Yes Crawler-Commons is definitely the better place. I patched it in Nutch for now so our crawler
could deal with this weirdness. 

Once fixed in CC, and if you upgrade Nutch' dependency, please close this ticket :)

Thanks!

> 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.
