Hi.
This is a conceptual question, i haven't tried yet.
The nutch version i am using is 2.0.
Suppose that a full crawl has been made and the nutch hsql database is
filled with all the data.
In my perception if i run nutch again, it should refetch all urls according
to the fetchSchedule rules.
The process responsible for marking the url's for fetching is the Generator
mapper but looking to the code i see
this:(org.apache.nutch.crawl.GeneratorMapper)
if (Mark.GENERATE_MARK.checkMark(page) != null) {
if (GeneratorJob.LOG.isDebugEnabled()) {
GeneratorJob.LOG.debug("Skipping " + url + "; already generated");
}
return;
}
The Generate_MARK is allways != null because after the first crawl the field
'MARKERS' of the database has:
__prsmrk__*1345638110-1053938230_gnmrk_*1345638110-1053938230_ftcmrk_*1345638110-1053938230.
The GenerateMark is allways present.
So, is my assumption correct or am i missing something?
