Hi,

You removed the Spark named config named "default", which is configured as the Spark config to use for your notebooks. We'd advise that you go in Admin > Settings > Spark and either select another config as the default for notebooks, or create a new config named "default" with no settings in it.

Hi Clement,

Thanks this worked!

Note that the removal of default config 'silently' happend when I set up Dataiku to run notebooks on GKE. Other users may see the same behaviour?
