Potentially dangerous intructions in "Ubuntu CE CPU Installation With Apt"

#1

I was installing CE CPU MapD on AWS LightSail instance following instructions step by step.
All went prettty well until I entered

sudo ufw disable
sudo ufw enable
sudo ufw allow 9092/tcp

It was pretty obvious in hidsight that I shot myself into foot by denying access with ssh (I was unable to connect to this particular instance ever again, so I just deleted it and created another anew), I should have added

sudo ufw allow 22

at that step. But maybe there should be some warning for inexperienced users like me

Hi,

Thanks for the note. Sorry for the issue.

Will get something added to the docs to help avoid issues in the future.
