I am trying to connect a shell to a spark master running in a quickstart VM (5.4.2). Locally it works fine but from a different node (also a quickstart VM) I am getting no conneciton. I am trying to connect with the following command: /usr/bin/spark-shell --master spark://192.168.1.31:7077. With nmap I see that the port is open but I am getting the following from the spark-shell:
INFO client.AppClient$ClientActor: Connecting to master akka.tcp://sparkMaster@192.168.1.31:7077/user/Master...
ERROR cluster.SparkDeploySchedulerBackend: Application has been killed. Reason: All masters are unresponsive! Giving up.
Anyone an idea what the issue might be? Is there any particularity of the quickstart VM that prevents this connection?
