Not able to create a directory in hadoop file system

Getting this problem while creating a directory in hadoop file system mkdir: Permission denied: user=ubuntu, access=WRITE, inode="/user/ubuntu":hdfs:supergroup:drwxr-xr-x

Solution

  • This can be achieved in two ways :-

    1) Run the command using hdfs user

    sudo -u hdfs hdfs dfs -mkdir /user/ubuntu/

    2) Change the ownership of the folders using the hdfs user so that you may not face problems while creating directories inside it or using it.

    sudo -u hdfs hdfs dfs -chowm ubuntu:ubuntu /user/ubuntu/

    Now user ubuntu will take the ownership of the ubuntu directory in Hadoop file system.
