Sam - it should run fine in docker, but if you are running a Linux docker on
Windows, I have heard that sometimes the environment can become flaky.
What you're seeing sounds like spark is failing to start.
You should be able to get Zeppelin to output a log for the entire spark
interpreter group. (What you pasted from is the Zeppelin log.) Can you tell us
what's in there?
