@felixcheung I'm managing Zeppelin with a Hadoop cluster which data access
control is introduced to via Apache Ranger because my company needs to control
each data access to our Hadoop cluster strictly. I found only the following 2
security issues about the Zeppelin cron scheduler:
1. https://github.com/apache/zeppelin/pull/2671
2. https://github.com/apache/zeppelin/pull/2676 (This PR)
In my opinion, it's enough to fix these 2 issues instead of reconsider the
whole access control of Zeppelin.
