Andreas Weise created ZEPPELIN-5049:
---------------------------------------
Summary: NullPointerException when running z.run(noteId,
paragraphId)
Key: ZEPPELIN-5049
URL: https://issues.apache.org/jira/browse/ZEPPELIN-5049
Project: Zeppelin
Issue Type: Bug
Components: zeppelin-interpreter
Affects Versions: 0.9.0
Reporter: Andreas Weise
Invoking z.run(noteId, paragraphId) does not execute the paragraph. Instead it
results in NPE:
I try to run z.z.run("2F7JQNWWH", "paragraph_1585928097689_1485809725") from
Note 2FMFEC5XF.
According to Interpreter Log the NoteId gets messed (it mentions the NoteId of
the Paragraph where I trigger z.run(...) from ):
RemoteInterpreterEventClient.java[runParagraphs]:273) - Fail to runParagraphs:
RunParagraphsEvent(noteId:*2FMFEC5XF*,
paragraphIds:[paragraph_1585928097689_1485809725],
