使用新脚本 bin/crawl - 跳过不同批次 id 的 url (null)

Question

我想用 Nutch 2.1 新的抓取脚本 bin/crawl 从我的 seed.txt 抓取很多网站。

问题是，每次我运行我的脚本时，它都不会获取或解析任何内容（没有 url），并显示消息“Skipoing [这里是具体的 url] 不同的批处理 id (null)”

以下是日志的一些输出：

Start old crawling linked TV:
InjectorJob: starting
InjectorJob: urlDir: /opt/ir/nutch/urls
InjectorJob: finished

看来注入url是没问题的

请问您知道问题出在哪里吗？我完全厌倦了这个工具的配置，并试图很好地使用它......

好的，解决方案是我使用了旧版本的 nutch (2.1)。更新到 2.2.1 后这个问题消失了。
