Can someone help a newbie??!!
I've setup nutch according to the tutorial
http://www.nutch.org/docs/en/tutorial.html
created a flat file called urls, edited conf/crawl-urlfilter.txt
but when I run the command I get:
[EMAIL PROTECTED] nutch-0.5]# bin/nutch crawl urls -dir crawl.test -depth 3
041026 102539 loading file:/root/install/nutch-0.5/conf/nutch-default.xml
041026 102539 loading file:/root/install/nutch-0.5/conf/crawl-tool.xml
041026 102539 loading file:/root/install/nutch-0.5/conf/nutch-site.xml
041026 102539 crawl started in: crawl.test
041026 102539 rootUrlFile = urls
041026 102539 threads = 10
041026 102539 depth = 3

Can anybody highlight the rookie mistake?
Many thanks,
Michael.
