Markus Jelsma commented on NUTCH-2335:
--------------------------------------
Sebastian, filtering and normalizing is still enabled by default yet in the
description you want to disable is by default. With this patch and no further
configuration changes our injector still filters everything.
> Injector not to filter and normalize existing URLs in CrawlDb
> -------------------------------------------------------------

> Key: NUTCH-2335
> URL: https://issues.apache.org/jira/browse/NUTCH-2335
> Project: Nutch
> Issue Type: Improvement
> Components: crawldb, injector
> Affects Versions: 1.12
> Reporter: Sebastian Nagel
> Assignee: Sebastian Nagel
> Fix For: 1.14
>
>
> With NUTCH-1712 the behavior of the Injector has changed in case new URLs are
> added to an existing CrawlDb:
> - before only injected URLs were filtered and normalized
> - now filters and normalizers are applied to all URLs including those already
> in the CrawlDb
> The default should be as before not to filter existing URLs. Filtering and
> normalizing may take long for large CrawlDbs and/or complex URL filters. If
> URL filter or normalizer rules are not changed there is no need to apply them
> anew every time new URLs are added. Of course, injected URLs should be
> filtered and normalized by default.
