Zeppelin notebook and user access

[#1]

Where can I set access to a zeppelin notebook? So far all users can see all the notebooks.

Is there a way of setting a proxy user? Example:

I log in to zeppelin as user USER1, who has access to a folder in hdfs /user/user1 I want to save my analysis results i made in zeppelin to that folder - /user/user1 I get an error saying zeppelin user has no access to this folder.

How can I fix this? adding zeppelin user as proxy user in HDFS conf file did not do the trick.

İf you use Ambari managed cluster go Ambari -> Zeppelin -> Configs -> shiro_ini_content section. Edit for new users, groups and passwords by changing text( at [users] section). For permission; open Zeppelin UI and related Notebook. There is note permission (top right corner) on each Notebook you can modify permissions from here.
