"Interpreter null not found" when a note is not bound to any interpreters

    Details

    • Type: Bug
    • Status: Open
    • Priority: Major
    • Resolution: Unresolved
    • Affects Version/s: 0.7.1, 0.7.2, 0.8.0
    • Fix Version/s: None
    • Component/s: None

      Description

      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:

      org.apache.zeppelin.interpreter.InterpreterException: paragraph_1491878547585_-790720711's Interpreter null not found
      	at org.apache.zeppelin.notebook.Note.run(Note.java:625)
      	at org.apache.zeppelin.socket.NotebookServer.persistAndExecuteSingleParagraph(NotebookServer.java:1781)
      	at org.apache.zeppelin.socket.NotebookServer.runParagraph(NotebookServer.java:1741)
      	at org.apache.zeppelin.socket.NotebookServer.onMessage(NotebookServer.java:288)
      

      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
