Hey Folks - Our Livy README.md indicates the following:
To run Livy, you will also need a Spark installation. You can get Spark releases at https://spark.apache.org/downloads.html. Livy requires Spark 2.4+. You can switch to a different version of Spark by setting the SPARK_HOME environment variable in the Livy server process, without needing to rebuild Livy. Do we have any variation on this setup at this point in the real world? What do your dev environments actually look like and how are you installing what versions of Spark as a dependency? Thanks! --larry
