-------------------------------------------
Summary: "Interpreter null not found" when a note is not bound to
any interpreters
Key: ZEPPELIN-2506
URL: https://issues.apache.org/jira/browse/ZEPPELIN-2506
Project: Zeppelin
Issue Type: Bug
Affects Versions: 0.7.1, 0.7.2, 0.8.0
Reporter: Ruslan Dautkhanov
When we setup a new user or upgrade a note, interpreter.json file is copied
from a template file. So "interpreterBindings" is empty or irrelevant to notes
that an upgraded user has. It causes following exception:
{noformat}
org.apache.zeppelin.interpreter.InterpreterException:
paragraph_1491878547585_-790720711's Interpreter null not found

It would be better to show error message *that the note is not bound to any
notes, and not let execute any paragraphs until this is fixed*.
If a paragraph has an explicit interpreter type defined, then this error is
slightly different but this does not change the matter
