Usama Tahir created NUTCH-2588:
----------------------------------
Summary: Getting status code x01 (unfetched) on more than 80%
crawled urls
Key: NUTCH-2588
URL: https://issues.apache.org/jira/browse/NUTCH-2588
Project: Nutch
Issue Type: Bug
Components: crawldb, fetcher
Affects Versions: 2.3.1
Environment: I am using apache nutch 2.3.1 with hadoop 2.7.6 and hbase
0.98.8 hadop2.
Operating System: Ubuntu 16.04
Reporter: Usama Tahir
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 2.8 lac.
when we analyze hbase table and check status codes of all urls we got round
about 1.4 lac urls having status code of x01 [un fetched]
it means 2.4 lac urls out of 2.8 lac 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.
