------------------------------------
Summary: Zeppelin Import/Clone doesn't set user in Paragraph
causing NPE
Key: ZEPPELIN-3309
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3309
Project: Zeppelin
Issue Type: Bug
Components: zeppelin-zengine
Affects Versions: 0.7.1, 0.7.0, 0.8.0, 0.9.0
Reporter: Greg Senia
Assignee: Greg Senia
Fix For: 0.9.0
Attachments: clone_failure.log.txt, clone_works.log.txt,
import_failure.log.txt, import_works.log.txt, orig_vs_clone.nofix.txt
When performing testing with Zeppelin 0.9.0/0.8.0 with importing notebooks
and/or cloning notebooks noticed NPE's being thrown. After performing some
debug for the past few days determined the cause is the fact that "user"
attribute is not being populated and "user" is used in many places including
binding interpreters and unbinding interpreters. The only workaround is to run
all the paragraphs which go and update the notebooks paragraph json sections. I
fixed this by during the Note.addCloneParagraph by passing AuthenticationInfo
in so that "user" is set.
I've attached log showing my debug statements I added both with and without the
fix and diff's of the notebook jsons missing the "user" attribute during the
clone/import.
Example of missing user attribute on clone:
