Empy Notebook file prevents Zeppelin from starting

[Boris Schminke <sc...@gmail.com>]

Hi,
if one replaces any of note.json files in Zeppelin Notebooks directory with
an empty one then Zeppelin server fails to start with very weird error.
Probably it should start and report that some notebook is corrupted. The
error is generated any time when note.json is not a valid JSON. I had one
of my notebooks corrupted after sudden power loss and then lost several
hours trying to understand why the Zeppelin daemon stopped working:(

Re: Empy Notebook file prevents Zeppelin from starting

[moon soo Lee <mo...@apache.org>]

Thanks for creating the issue.
I have created a patch to skip invalid json file.
https://github.com/apache/incubator-zeppelin/pull/786
Please share notebook file corruption happens to you again.

Thanks,
moon

Re: Empy Notebook file prevents Zeppelin from starting

[Boris Schminke <sc...@gmail.com>]

Hi, moon

I used Zeppelin 0.5.6 binaries from the site to reproduce the bug. Probably
I was extremely unlucky to corrupt this file:) The corruption itself was
related to power supply problem I guess, so it doesn't look reproducible.
I've filed the issue to JIRA.

Thanks,
Boris

Re: Empy Notebook file prevents Zeppelin from starting

[moon soo Lee <mo...@apache.org>]

Hi,

That seems problem Zeppelin can not start when there're invalid json file.
Thanks for sharing the problem. Do you mind creating an issue for it?

by the way, after https://issues.apache.org/jira/browse/ZEPPELIN-454 being
resolved (0.5.6-incubating), i thought it's hard to note.json being
corrupted. Which version of Zeppelin are you using?

Thanks,
moon
