Subject [jira] [Created] (NUTCH-2213) CommonCrawlDataDumper saves gzipped body in extracted form

             Summary: CommonCrawlDataDumper saves gzipped body in extracted form
                 Key: NUTCH-2213
             Project: Nutch
          Issue Type: Bug
          Components: commoncrawl, dumpers
            Reporter: Joris Rau
            Priority: Critical

I have downloaded [a WARC file|]
from the common crawl data. This file contains several gzipped responses which are stored
plaintext (without the gzip encoding).
I used [warctools|] from Internet Archive to extract
the responses out of the WARC file. However this tool expects the Content-Length field to
match the actual length of the body in the WARC ([See the issue on github|]).
I have not been using Nutch and can therefore not say which versions are affected by this.
After reading [the official WARC draft|]
I could not find out how gzipped content is supposed to be stored. However probably multiple
WARC file parsers will have an issue with this.
It would be nice to know whether you consider this a bug and plan on fixing this and whether
this is a major issue which concerns most WARC files of the Common Crawl data or only a small
