Hello,
Can't speak for active maintenance, but Hue is open-source, so feel free to check the commit logs yourself. :)
Spark Notebooks will require a running Livy Server <
http://livy.incubator.apache.org/> which can be configured with Spark 1.3 and later. Personally, I have tested a Spark2 configured Livy 0.3 server, and Hue seems fine with it.
If you are solely looking for notebook alternatives and not needing the other Hue features, you can look into either Apache Zeppelin or Apache Toree w/ Jupyter.
