写文件出错~求问

[iama...@gmail.com]

Caused by: org.apache.hadoop.ipc.RemoteException: org.apache.hadoop.security.AccessControlException: Permission denied: user=hadoop, access=WRITE, inode="OuyangYiqun":OuyangYiqun:cs402:rwxr-xr-x

看起来像是拒绝写入了的样子~

是什么错啊？为了找错还需要我补充什么细节我再贴出来

是代码写错了还是设置出错了

同学你好，我是助教，你直接把代码发给我吧，不用发组里了。

你是不是写到public里面了。。。。。我也犯过这个错误。貌似只有cs402文件夹下的有修改权限？

那我发作业那个邮箱里面啦！谢谢助教！

路过猜测是你在mapper或reducer中直接new了jobconf而没有获得任务的conf吧.

在出错处加一行

conf.set("hadoop.job.ugi","OuyangYiqun,cs402");

就好
