windows下eclipse基于hadoop配置注意项

具体 http://www.cnblogs.com/xia520pi/archive/2012/05/20/2510723.html

出现security.UserGroupInformation: PriviledgedActionException as:wsp cause:java.net.UnknownHostException: unknown host: master

Exception in thread "main" java.net.UnknownHostException: unknown host: master错误

需更改windows下hosts配置 与linux下的hosts文件保持一致,,

运行时需点run as 〉run config 点类名 点击argument 在框中加入输入输出文件路径


出现java.net.SocketTimeoutException: 480000 millis timeout while waiting for channel to be ready for write. ch : java.nio.channels.SocketChannel[connected local=/  以及sockettimeout时先查看是否关闭防火墙。。
