[ http://issues.apache.org/jira/browse/NUTCH-273?page=comments#action_12451159 ] Johannes Zillmann commented on NUTCH-273: -----------------------------------------
As a consequence of this issue a crawl could be permanently blocked. Imagine the top 5 mio of crawldb are all redirect urls whose targets has already been fetched. Then you can successfully generate 5 mio, fetch 5 mio and parse 5 mio, but after an update of the crawldb, nothing has happened! > When a page is redirected, the original url is NOT updated. > ----------------------------------------------------------- > > Key: NUTCH-273 > URL: http://issues.apache.org/jira/browse/NUTCH-273 > Project: Nutch > Issue Type: Bug > Components: fetcher > Affects Versions: 0.8 > Environment: n/a > Reporter: Lukas Vlcek > > [Excerpt from maillist, sender: Andrzej Bialecki] > When a page is redirected, the original url is NOT updated - so, CrawlDB will > never know that a redirect occured, it won't even know that a fetch > occured... This looks like a bug. > In 0.7 this was recorded in the segment, and then it would affect the Page > status during updatedb. It should do so 0.8, too... -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira ------------------------------------------------------------------------- Take Surveys.
