Affects Version/s: 0.7.1
Fix Version/s: None
I've read the overview docs on interpreters at http://zeppelin.apache.org/docs/0.7.1/manual/interpreters.html and http://zeppelin.apache.org/docs/0.7.1/development/writingzeppelininterpreter.html but I'm still confused! E.g., at http://zeppelin.apache.org/docs/0.7.1/manual/interpreters.html#interpreter-binding-mode it says "In 'isolated' mode, each notebook will create new Interpreter process." Does that mean a new JVM process, or a new process (with its own interpreter instance) in the same JVM as the Interpreter Group?
Please can we have a simple explanation in one place about the relationship between the following entities:
Spark Driver program
Interpreter binding mode for notebooks
A diagram showing the relationship between these entities for the 3 different interpreter binding notes (shared, scoped, isolated) would be extremely helpful. This would help users understand the implications of the different modes - for example, whether they can share a SparkContext and hence data or variables between different notebooks. Or what would happen to another user's notebook if a given Interpreter Group is restarted. Thanks!
