Exception in thread "main" java.lang.IllegalArgumentException: Fetcher: No agents listed in 'http.agent.name' property.

每次我运行 ./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 &nutch-default.xml 设置.

Every time i run ./nutch crawl urls -dir crawl -depth 3 -topN 5 . nutch decides to throw this error. I have both my nutch-site.xml & nutch-default.xml set with.

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

去掉描述以使其更易于阅读.但是我看不到可以指定代理名称的其他位置.如果有人有任何建议，我将不胜感激.

Took the description out to make its easier to read. But I fail to see where else the agent name can be specified. if anybody has any advice I would be grateful.

推荐答案

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

using 1.3? If so make sure you changed nutch-site.xml (and not default) in runtime/local/confChanging the conf in NUTCH_HOME/conf won't be copied to the runtime dirs unless you rebuild with ant.
