Notebook spawned in Yarn but killed after timeout

Excellent, anything YarnSpawner-specific is a much smaller zone for fixes! I will get to that right away and see what I can figure out. Do you think it’s worth waiting to fix everything I can fix before filing that issue about the absence of notebook? I want to make sure I can give the best possible picture to the devs.

Thank you again @mahendrapaipuri for all the help you have been giving me for this!
