Usama Tahir updated NUTCH-2588:
-------------------------------
Description:
when i run nucth with external links enabled, seed of 10 urls and number of
rounds 5 using command
bin/crawl <seed_path> <db> [<solr url>] <number of rounds>
i have default topN value which is 50000
the process completes execution in 11 to 12 hours and generated urls rows of
about 280000.
when we analyze hbase table and check status codes of all urls we got round
about 242000 urls having status code of x01 [un fetched]
it means 242000 urls out of 280000 which nutch extracted remains unfetched.
after some debugging of nutch and analyzing its logs i found that those urls
which have status code of x01 are not even tried to fetch.
is this the bug of nutch or something configuration issue?
kindly resolve my issue as soon as possible.
