权限在hdfs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，但是之后当我要将数据上传到hdfs时，它会给出错误消息 Permission Denied 。

来自终端的消息：

  hduser @ ubuntu：/ usr / local / hadoop $ hadoop fs -put / usr / local / input-data / / input 
 put：/ usr / local / input-data（权限被拒绝）
 
 hduser @ ubuntu：/ usr / local / hadoop 
  

使用sudo并添加hduser to sudouser：
$ b $ pre $ hduser @ ubuntu：/ usr / local / hadoop $ sudo bin / hadoop fs -put / usr / local / input-data / / inwe
put：org.apache.hadoop.security.AccessControlException：权限被拒绝：user = root，access = WRITE，inode =：hduser：supergroup：rwxr-xr-x

hduser @ ubuntu：/ usr / local / hadoop $


解决方案

我通过禁用dfs权限来解决这个问题将以下属性代码
添加到conf / hdfs-site.xml中

 < property> 
<名称> dfs.permissions< /名称> 
<值> false< /值> 
< / property> 
  

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.

Message from terminal with command:

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$ 

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$ 

解决方案

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>
