--------------------------------
Component/s: parser
indexer
fetcher
> Nutch doesn't index all URLs found
> ----------------------------------
>
> Key: NUTCH-2230
> URL: https://issues.apache.org/jira/browse/NUTCH-2230
> Project: Nutch
> Issue Type: Bug
> Components: fetcher, generator, indexer, parser
> Affects Versions: 2.3.1
> Environment: MongoDB with WiredTiger storage engine (3.2 but probably
> affects other versions as well)
> Reporter: Aaron Cosand
>
> The initial query run by the generator task, against mongodb, doesn't force
> ordering by _id. This causes an incorrect selection of ranges for successive
> map-reduce related queries. The successive queries do appear to be getting
> run in the correct order since _id is always indexed, but they should also
> explicitly specify a sort, since you are not guaranteed a particular order
> otherwise. I didn't dig deep enough to see if the root of the problem is
> with nutch or gora, and whether it only affected mongo or could affect other
> databases as well.
