That port range is used by interactive sessions for the server and client to communicate. The default range is 10 ports, so IIUC if you want to run more than 10 concurrent interactive sessions you'll need to extend that range. If I misunderstood this someone else can feel free to correct me.

Hi All, Can someone explain what this is livy.rsc.launcher.port.range = 10000~10110 Sometimes I have all the 10 ports open I am not sure why? How do I make sure this doesn't happen? Thanks!
