》》》》》》》》》我的nutch配置如下
nutch-site.xml
     
         http.agent.name
         My Nutch Spider
     
regex-urlfilter.txt加了
# accept anything else
+^http://([a-z0-9]*\.)*apache.org/
              
               
               

            connection exception: connection failure
阿是数据库没有连上，看一下配置，再看一下数据库有没有打开。

            原来如此，2.0是一定要连接数据库才能用的，明白了

看了你博客的文章，nutch分析的真好，对我帮助很大，我还有一个问题：
nutch2.0可以存储一个url的多个版本吗，还是只存最新的
我看到gora-hbase-mapping.xml有这样的定义

不知道maxVersions是不是指版本数，是不是改了这个设置就可以存多版本了
