I agree - have also been thinking about the same problem in the context of running zeppelin against a secure kerberized hadoop cluster.
There are a couple concerns here: 1. authentication, both for the zeppelin server and for interpreters that need it 2. isolating the code for different users from each other - for example by running an interpreter for each user 3. sharing interpreters across note evaluations - this is likely an issue even without multiple users but multiple tabs for the same user. It is already taken care of by the interpreter scheduler (by returning a FIFO or parallel scheduler with the specified max concurrency option), is this correct? Thanks!

But it should be more about accessing the instance than having multiple users. One way could be launching multiple zeppelin instances, I think Kevin is doing something similar. One thing to realize however is that it doesnt create separation at the data layer On Mar 28, 2015 1:53 AM, "RJ Nowling" <rnowl...@gmail.com<mailto:rnowl...@gmail.com>> wrote: I'll report back if I'm successful with the approach I've mentioned.

Will the nginx reverse proxy support web sockets as well? Ideally we’d have isolated SparkContexts so users aren’t trampling over each other. Honestly I think it’d be good to have the option of starting a new SparkContext per notebook as well or using the model Databricks has where you “attach” a notebook to a cluster.

I want to provide isolation between users. I'm considering the following approach: * Run Zeppelin under each user's account with its own set of ports * Use nginx as a reverse proxy for providing authentication Has anyone done anything similar? Any better alternatives? Thanks! RJ
