ConfX created ZEPPELIN-5941:
-------------------------------
Summary: Missing null check in Notebook
Key: ZEPPELIN-5941
URL: https://issues.apache.org/jira/browse/ZEPPELIN-5941
Project: Zeppelin
Issue Type: Bug
Reporter: ConfX
Attachments: reproduce.sh
h2. What happened:
Got NullPointerException when initializing a Notebook.
h2. Where's the bug:
At the end of the constructor of {{Notebook}} a rebuild takes place:
{noformat}
if (conf.isIndexRebuild()) {
noteSearchService.startRebuildIndex(getNoteStream());
}{noformat}
The problem with this is that if {{noteSearchService}} is null, the code would
throw an NPE out of nowhere with no message.
h2. StackTrace:
{noformat}
java.lang.NullPointerException,
at org.apache.zeppelin.notebook.Notebook.<init>(Notebook.java:112),
at org.apache.zeppelin.notebook.Notebook.<init>(Notebook.java:165),
at
org.apache.zeppelin.notebook.NotebookTest.testRevisionSupported(NotebookTest.java:124),{noformat}
h2. How to reproduce:
(1) Set {{zeppelin.search.index.rebuild }} to {{true }}
(2) Run test: {{org.apache.zeppelin.notebook.NotebookTest#testRevisionSupported
}}
For an easy reproduction, run the reproduce.sh in the attachment.
We are happy to provide a patch if this issue is confirmed.
