Julien Nioche commented on NUTCH-1708: -------------------------------------- I like the approach and this would be the best way of solving the issue. +1 to commit Re-field "orig" in 2.x : sounds like a duplicate of 'id' indeed. Let's do its removal separately Thanks > use same id when indexing and deleting redirects > ------------------------------------------------ > > Key: NUTCH-1708 > URL: https://issues.apache.org/jira/browse/NUTCH-1708 > Project: Nutch > Issue Type: Bug > Components: indexer > Affects Versions: 1.7 > Reporter: Sebastian Nagel > Fix For: 1.9 > > Attachments: NUTCH-1708-2x-v1.patch, NUTCH-1708-trunk-v1.patch > > > Redirect targets are indexed using "representative URL" > * in Fetcher repr URL is determined by URLUtil.chooseRepr() and stored in > CrawlDatum (CrawlDb). Repr URL is either source or target URL of the redirect > pair. > * NutchField "url" is filled by basic indexing filter with repr URL > * id field used as unique key is filled from url per solrindex-mapping.xml > Deletion of redirects is done in IndexerMapReduce.reduce() by key which is > the URL of the redirect source. If the source URL is chosen as repr URL a > redirect target may get erroneously deleted. > Test crawl with seed {{http://wiki.apache.org/nutch}} which redirects to > {{http://wiki.apache.org/nutch/}}. DummyIndexWriter (NUTCH-1707) indicates > that same URL is deleted and added: > {code} > delete http://wiki.apache.org/nutch > add http://wiki.apache.org/nutch > {code} -- This message was sent by Atlassian JIRA (v6.2#6252)
