Hello I know that 8080 is a pretty common port for web app but when running Zeppelin server on a machine hosting a Spark master, it conflicts with the Spark master UI running on 8081 so the Zeppelin web socket fails.
Does it make sense to default to another port than 8080 to avoid all possible conflicts (not only with Spark master, a lot of webapp defaults their port on 8080) Regards Duy Hai DOAN
