Permission denied at hdfs

Question

I am new to hadoop distributed file system. I have completely installed hadoop single node on my machine, but 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$ 

Can someone help me solve this error?

You can spolve this by adding below property code to conf/hdfs-site.xml

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