Github user prabhjyotsingh commented on the issue: https://github.com/apache/zeppelin/pull/1426 Here is before and after of this PR that I observe, and I see these 2 changes - now it does not stream output, i.e. it waits for the entire paragraph execution to be finished, and returns result. - and I see empty line between "1" and "2" where I wrote "Thread.sleep()", not a big deal, but it wasn't earlier.
