I'm having this same issue with zeppelin 0.7.3 + livy 0.5.0 + spark 2.2.1.
I have not yet verified that zeppelin master resolves this issue, but from
inspection I would think that @thesuperzapper is right that the issue would
persist. I would think that any invocation of `SparkUI.appUIAddress()` would
throw a `NoSuchMethodException`, and zeppelin master still seems to be making
those calls (specifically from `LivySparkInterpreter`). @zjffdu Do you have
any notion as to why your interpreter would not be throwing an exception?
