Subject Re: LinkDB size difference
Date Tue, 01 Sep 2009 09:48:55 GMT
you can dump the linkdb and analyze where it differs.
my guess is, that you have different urls there because crawl uses
crawl-urlfilter.txt to filter urls
and fetch uses regex-urlfilter.txt.
so different filters.
i cant explain why. i have not implemented this. i have only experienced
the difference myself.

how to dump the linkdb:

reinhard@thord:>bin/nutch readlinkdb
Usage: LinkDbReader <linkdb> {-dump <out_dir> | -url <url>)
        -dump <out_dir> dump whole link db to a text file in <out_dir>
        -url <url>      print information about <url> to System.out
