我在Windows中使用hadoop，并且已经配置好了所有东西(安装cygwin，无密码ssh等。)
我已经在WC.jar中编译了wordcount程序并尝试运行。它可以在独立模式下完美运行..但在完全分布式模式下，它可以提供FileNotFoundException
请查看日志，然后告诉我这是怎么回事。
我已经开始在MACH1中进行dfs和mapreduce了。 (那是我的主人)

谢谢。
最佳答案
我想我以前可能已经见过这种异常，但是我无法访问旧日志进行确认。我通过重新格式化namenode 来解决了FileNotFoundException的问题。您可能需要检查名称节点日志中是否存在“不一致状态”，以在重新格式化之前确认原因。
