Github user lresende commented on the issue: https://github.com/apache/zeppelin/pull/747 Ok, looks like the hanging I was seeing was mostly a local issue in my Spark conf and is now fixed. I have Zeppelin and Spark built with Scala 2.11, and the tutorial notebook works well, I can also update the interpreter properties and that works well as well. Export is working, but Importing as mentioned by @chbrown just don't do anything. I will try with master and see if this is an issue specific to the scala 2.11 branch or not. Btw, I am not sure if the CI build these days is helping or not, as it's very hard to trust that failures are related to changes.
