I followed this tutorial for installation of Hadoop. Unfortunately, when I run the dfs namenode -format script - The following error was printed on console:

but at the end i see this msg

dfs namenode -format

mkdir: cannot create directory ‘/home/hdoop/hadoop-3.2.1/logs’: Permission denied
ERROR: Unable to create /home/hdoop/hadoop-3.2.1/logs. Aborting.

./start-dfs.sh

  1. Create Directory :- Create "logs" directory by using root access yourself.As in this case directory was logs create it at /home/hdoop/hadoop-3.2.1/ (eg. "/home/{username}/{extracted hadoop directory}/" )
  2. Give Access of Directory :- Make it accessible by using sudo chmod 777 {directory location} In this case - sudo chmod 777 /home/hdoop/hadoop-3.2.2/logs To see it worked in my case see following image : solved it by giving access of following directory
