I think Vincent's option 1 is the way to go at this stage. Basically, in a
multi-users environment, every users should have their own storage and
processing. So far Zeppelin has not seen to be able to isolate users

My question is,
1. I am using windows for client which means Zeppelin is installed on
windows. Is their any downside or limitation?
2. Even installed on individual desktop, I still like to have
authentication for login as users may access their desktop remotely from
browser. Any idea how to set this up?
3. I am using MapR cluster. Does anyone have similar experiences on how to
config secure cluster with zeppelin in windows? Also is it possible to set
up an admin user for every desktop so that only I can change the
