Empty Nutch crawl list

问题:

I'm trying to run a crawl using Nutch in Eclipse.

I'm using a file called urls, and it contains

http://www.google.com/

However, when I run the project, the Generator class tells me that:

"0 records selected for fetching, exiting"

How can I solve this issue?

I've followed these documentations:

http://wiki.apache.org/nutch/RunNutchInEclipse1.0

http://wiki.apache.org/nutch/NutchTutorial

Any help would be greatly appreciated.

回答1:

I recently ran into this issue and found that most responses concerned the (regex|crawl)-urlfiters.txt. Another thing to check is your '-topN' settings. This needs to be large enough for the generator to pass all filters.

I hope this helps.

Its most likely your regex-urlfilter.xml. Try using this and see if it fixes the problem
