> Key: NUTCH-2456
> URL: https://issues.apache.org/jira/browse/NUTCH-2456
> Project: Nutch
> Issue Type: Bug
> Components: indexer
> Affects Versions: 1.13
> Reporter: Yossi Tamari
> Priority: Critical
> Fix For: 1.14

>
> If http.redirect.max is set to a positive value, the Fetcher will follow
> redirects, creating a new CrawlDatum.
> If the redirected URL is fetched and parsed, during indexing for it we have a
> special case: dbDatum is null. This means that in
> [https://github.com/apache/nutch/blob/6199492f5e1e8811022257c88dbf63f1e1c739d0/src/java/org/apache/nutch/indexer/IndexerMapReduce.java#L259]
> the document is not indexed, as it is assumed it only has inlinks (actually
> it has everything but dbDatum).
> I'm not sure what the correct fix is here. It seems to me the condition
> should use AND instead of OR anyway, but I may not understand the original
> intent. It is clear that it is too strict as is.
> However, the code following that line assumes all 4 objects are not null, so
> a patch would need to change more than just the condition.
