Github user kjmrknsn commented on the issue: https://github.com/apache/zeppelin/pull/2676 @Leemoonsoo > In case of a note is cron scheduled and doesn't want anyone else edit the notebook other than the cron execution user, wouldn't 'owner' of note remove users from 'writers' and add them in 'readers'? Yes, ideally, every Zeppelin user should do so. However, it's not realistic to force every Zeppelin user to do so because almost all of them do not realize this kind of security issue, it takes a huge effort to do so if there are a lot of users and notebooks, or they might forget to do so. Thus, it is reasonable and secure to do this kind of permission control at the Zeppelin system side not the Zeppelin user side.
