I've begun the HDP Migration Lab, and the very first instruction (after logging into the VM as root, is to ssh into node1) fails and returns this error message: ssh:connect to host node1 port 22: No route to host. The documented instructions (in Installing HDP) seem to be missing one or more critical preceeding instructions.
In the /etc/hosts file, node1 has the IP address 172.17.0.5. After installing nmap, and running 'nmap -sS -F 172.17.0.5' the remitted message states that 'Host seems down'. And 'nmap -Pn 172.17.0.5' remits the message that '0 hosts up'. These commands appear to indicate that node1 (docker container) is not running.
In the root home directory, there is an install_course.sh script. Thinking that running this script is the missing initial instruction, I ran that script, but it failed with the following error message: Usage: install_course.sh <course_id>. What value must be assigned to course_id in order for that script to execute successfully?
