Installation FAILED with errors.

Installation stopped before any changes were made.
install_vertica script failed with exit code 1 ..........................[FAIL]

Cause

sudo su -root was not being used

It's asking for password during install.

Resolution

Rerun the upgrade using "sudo su - root"

sudo su - root ./dr_install.sh

Additional Information

If using sudo, "sudo su root" or "sudo -s" cannot be used.

The correct syntax would be  "sudo su  - root", otherwise SUDO_USER is set still.
