> -----------------------------------------------------
>
> Key: NUTCH-2328
> URL: https://issues.apache.org/jira/browse/NUTCH-2328
> Project: Nutch
> Issue Type: Bug
> Components: generator
> Affects Versions: 2.2, 2.3, 2.4, 2.2.1, 2.3.1, 2.5
> Environment: Ubuntu 16.04 / Hadoop 2.7.1
> Reporter: Arthur B
> Labels: fails, generator, subsequent
> Attachments: generator-issue-static-count.patch
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Given a topN parameter (ie 10) the GeneratorJob will fail to generate
> anything new on the subsequent runs within the same process space.
> To reproduce the issue submit the GeneratorJob twice one after another to the
> M/R framework. Second time will say it generated 0 URLs.
> This issue is due to the usage of the static count field
> (org.apache.nutch.crawl.GeneratorReducer#count) to determine if the topN
> value has been reached.
