主题: Re: Aborting with 10 hung threads？
so fetch does hang when there is nothing for it to fetch. the most
likely thing that has happened here is that your inject command did not
go through successfully. you can check it by looking in to your hbase
and see if the webpage table has been created and has values (your urls
that you injected) in it. alliteratively you can just run 'nutch readdb
-stats' and see what you get. if there was nothing there double check
your config files.
