> Currently, the kernel creates and stores the SparkSession in a field to share between interpreters. If the user closes a SparkSession and creates a new one, then the Kernel still returns the original. Users may need to restart Spark sessions for long-running notebooks or to deal with Spark errors without losing datasets that have been pulled back to the notebook.
> I think that Toree should always return the current Spark session by calling {{SparkSession.builder.getOrCreate}}.
