Hi,
I have Zeppelin up and running for a while and created several notebooks that
ran fine before.
Starting today however for some reason all the notebooks refuse to run – they
get an error.
Looking at the logs, this is the error:

NotebookServer.java[onMessage]:100) - RECEIVE << RUN_PARAGRAPH

What changed? It seems to have something to do with the list of interpreters.
The above log was with the Zeppelin Tutorial notebook, running the very first
paragraph.
Any suggestions?

P.S. I also checked the start up logs to make sure it picked up the configs
correctly. Looks like it found the interpreters:
