• if you get the below error when you enter password
  $ sudo nano .bashrc

  [sudo] password for hdoop:

  hdoop is not in the sudoers file. This incident will be reported

  *********solution*********
  su –
  
  This will switch you to the root user account.
  
  Type the following command and press Enter:

  visudo
  
  This will open the sudoers file in the Nano text editor.
  
  Scroll down to the end of the file and add the following line:

  your_username ALL=(ALL) ALL
  your_username is hadoop if you followed exactly what he did

  Save the changes to the sudoers file by pressing "Ctrl+X", then "Y", and finally "Enter".
  it will take you back to the orginal page than Enter exist
  Now try entering the password again, it should work

• sir i am not able to start namenode on local host ,it is starting on my virtual machine and at the end it is showing permission denied

• @11:20
  JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
  in above "8" might be wrong
  first put "update-alternatives –list java"
  u might get "/usr/lib/jvm/java-11-openjdk-amd64/bin/java"
  so the number is "11" not "8"
  so update the command @11:20 to
  JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
