怎样使nutch从一个失败的process开始

Well, you can not. However, you have two choices to proceed:

• 1) Recover the pages already fetched and than restart the fetcher.

  • You'll need to create a file fetcher.done in the segment directory an than: , and . Assuming your index is at /index

    % touch /index/segments/2005somesegment/fetcher.done 
    
    % bin/nutch updatedb /index/db/ /index/segments/2005somesegment/
    
    % bin/nutch generate /index/db/ /index/segments/2005somesegment/
    
    % bin/nutch fetch /index/segments/2005somesegment

    All the pages that were not crawled will be re-generated for fetch. If you fetched lots of pages, and don't want to have to re-fetch them again, this is the best way.

  2) Discard the aborted output.

  • Delete all folders from the segment folder except the fetchlist folder and restart the fetcher.
