我正在尝试在
Windows机器上使用Nutch使用Solr,我收到以下错误：
原文链接：https://www.f2er.com/windows/365267.htmlException in thread "main" java.io.IOException: Failed to set permissions of path: c:\temp\mapred\staging\admin-1654213299\.staging to 0700
从我学到的很多线程中,nutch似乎使用了hadoop做了一些chmod魔法,它可以在unix机器上运行,但不能在windows上使用.
这个问题现在存在一年多了.我找到了一个线程,其中显示了代码行并提出了修复.我真的只有一个有这个问题吗？是否所有其他人都在创建自定义构建以便在Windows上运行nutch？或者是否有一些选项可以禁用hadoop或其他解决方案？也许是另一个爬行器而不是nutch？
非常感谢.
