Upgrading HDP from 18.104.22.168-2041 to 2.3 we do not have root access. Instead we are using dzdo. Prior to upgrade and to avoid pain during upgrade, I am asking our community to share any insights I should know of prior to running upgrade using dzdo.
I don't exactly have a solution. What I have is standard procedure which should take place prior to any upgrade. Test your methods in an environment prior to production upgrade. Best way to determine what issues you may encounter in prod.
