我在Windows计算机上尝试用户的Solr与Nutch的,我发现了以下错误:
Exception in thread "main" java.io.IOException: Failed to set permissions of path: c:\temp\mapred\staging\admin-1654213299\.staging to 0700
从大量的线程我了解到,那至极的Hadoop似乎被Nutch的使用做了一些搭配chmod魔力,将UNIX机器上工作,但无法在Windows。
存在现在一年多了这个问题。 我发现一个线程,其中示出的代码行,并提出一个修补。 我真的只放置了一个谁拥有这个问题? 是否所有的人创造一个自定义生成为了在Windows上运行Nutch的? 或者是有一些选项来禁用Hadoop的东西或其他解决方案? 也许另一个履带比Nutch的?
非常感谢。 鲍里斯
下面是我在做什么的堆栈跟踪....
