    Hi, please keep the thread on topic - the OP is asking about why they can't use sudo/edit the sudoers file

    Thanks

    Is the account you are trying to use sudo with the first account that was created during intsall, or is it an account created later?

    Can you post the output of the command "id"?

    Please see the questions in my last post.

    I don't think you are supposed to be logging in as hadoop. Try logging in as the username you gave during the install. I don't think hadoop should be in sudoers - should not have the right to switch to root.

    OK, let's explain a bit more. The first user created during install is automatically given the right to use sudo to raise their privilege. Other users created later are not, and it you want them to be able to use sudo you have to add them to the adm group. But you should only put trusted users in the adm group, and should not put applications such as hadoop in there. Applications, especially network-active ones, should not have that ability in case they contain a bug that allows remote exploits.
