Thanks! But if I just delete the webdb.old directory and recrawl, the following exception will happen: run java in J:\Java\jdk1.5.0_06 060709 094218 parsing file:/D:/cygwin/home/nutch-0.7.2/conf/nutch-default.xml 060709 094218 parsing file:/D:/cygwin/home/nutch-0.7.2/conf/crawl-tool.xml 060709 094218 parsing file:/D:/cygwin/home/nutch-0.7.2/conf/nutch-site.xml 060709 094218 No FS indicated, using default:local Exception in thread "main" java.lang.RuntimeException: fqjoke2 already exists. at org.apache.nutch.tools.CrawlTool.main(CrawlTool.java:121)
It's very strange! All the crawl jobs I can do before now can't work, always show the above exception. Regards!
