我使用Hadoop在Windows和我已经配置好的一切（安装了cygwin，密码的ssh等）Hadoop的Windows中：文件中未发现异常
我编译在WC.jar的单词计数程序并试图跑步。它在独立模式下完美运行..但在完全分布模式下，它给出FileNotFoundException
请查看日志并告诉我它有什么问题。 我已经开始了MACH1中的dfs和mapreduce。 （那是我的主人）

谢谢。
向我们展示[SSCCE]（http://sscce.org/）代码，您可以在其中调用'DistributedCache.addCacheFile'。请参阅[这里]（http://stackoverflow.com/questions/3219012/filenotfoundexception-when-using-hadoop-distributed-cache）以获得可能的答案。 – opyate 2011-06-30 22:42:35
