Nutch的路径错误

http://wiki.apache.org/nutch/NutchTutorial 和http://www.nutchinstall.blogspot.com/Nutch的路径错误

当我走命令

bin/nutch crawl urls -dir crawl -depth 3 -topN 5

我有

LinkDb: adding segment: file:/C:/cygwin/home/LeHung/apache-nutch-1.4-bin/runtime/local/crawl/segments/201203

看起来像没有所需的parse_data子文件夹段内有一些目录。你有没有运行爬网之前，然后删除一些目录？ – javanna 2012-03-02 09:18:12

我有同样的问题 – Aftershock 2012-03-21 21:37:53

我有类似的问题。我删除了数据库和目录。之后，它运行良好。

它似乎适合我。但是如果我爬了好几天，那就不会那么好。 – MrROY 2012-03-23 07:36:00
