             Summary: Notebook interpreter restart makes running notebooks abort
                 Key: ZEPPELIN-3027
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3027
             Project: Zeppelin
          Issue Type: Bug
          Components: Interpreters
    Affects Versions: 0.7.3, 0.7.2
            Reporter: Cristina Luengo Agullo
            Priority: Major


When I set the isolation mode of an interpreter to:
- Per user: isolated
- Per note: isolated

I would expect separate interpreter sessions and processes for at least each 
notebook. But this behaviour is not observed in the following scenario:

'user1' has 'notebook1' bound to an interpreter 'i'. When 'user1' is running 
'notebook1', 'user2' decides to restart the interpreter 'i' from another 
'notebook2' (in the 'Interpreter binding option).

The behaviour I would expect is for 'notebook1' to finish correctly. But when 
interpreter 'i' is restarted, 'notebook1' finishes stops with 'ABORT'. 

The same behaviour is observer with any combination of the binding mode of the 
interpreters.
