每次我跑./nutch crawl urls -dir crawl -depth 3 -topN 5.nutch决定抛出这个错误.我有我的nutch-site.xml和nutch-default.xml设置.

 <property>
  <name>http.agent.name</name>
  <value>blah</value>
  </property>

进行了描述,使其更容易阅读.但我没有看到可以指定代理名称的其他位置.如果有人有任何建议我会很感激.

使用1.3？如果是这样,请确保在runtime/local/conf中更改了nutch-site.xml(而不是默认值)更改NUTCH_HOME/conf中的conf将不会复制到运行时目录,除非您使用ant重建.
