hdfs 权限被拒绝 [英] Permission denied at hdfs

问题描述

我是 hadoop 分布式文件系统的新手，我已经在我的机器上完成了 hadoop 单节点的完整安装.但是之后，当我将数据上传到 hdfs 时，它给出了一条错误消息 Permission Denied.

I am new to hadoop distributed file system, I have done complete installation of hadoop single node on my machine.but after that when i am going to upload data to hdfs it give an error message Permission Denied.

来自终端的命令消息:

hduser@ubuntu:/usr/local/hadoop$ hadoop fs -put /usr/local/input-data/ /input
put: /usr/local/input-data (Permission denied)

hduser@ubuntu:/usr/local/hadoop$ 

使用 sudo 并将 hduser 添加到 sudouser 后:

After using sudo and adding hduser to sudouser:

hduser@ubuntu:/usr/local/hadoop$ sudo bin/hadoop fs -put /usr/local/input-data/ /inwe
put: org.apache.hadoop.security.AccessControlException: Permission denied: user=root, access=WRITE, inode="":hduser:supergroup:rwxr-xr-x

hduser@ubuntu:/usr/local/hadoop$ 

推荐答案

我通过禁用 dfs 权限临时解决了这个问题.通过添加以下属性代码到 conf/hdfs-site.xml

I solved this problem temporary by disabling the dfs permission.By adding below property code to conf/hdfs-site.xml

<property>
  <name>dfs.permissions</name>
  <value>false</value>
</property>
