no more URLs to fetch

Generator: 0 records selected for fetching, exiting ...

Stopping at depth=0 - no more URLs to fetch.

出现上面的错误一般都会是nutch/conf/crawl-urlfilter.txt中的配置出现的不可预见的错误

我在网上找了好多配置发现

# accept hosts in MY.DOMAIN.NAME
+^http://([a-z0-9]*/.)*360buy.com/

([a-z0-9]*/.)里的/这个写错了，正确的如下：

# accept hosts in MY.DOMAIN.NAME
+^http://([a-z0-9]*.)*qq.com/
