Would like to understand how to validate/check/test mode of deployment (Client mode or cluster mode) in Standalone cluster.I understand by setting values in conf, I can view it on spark Web UI environment variables but it does not help me in understanding impact of deployment mode. I tried running application from machine on which master/executor were running and from local laptop. But I could not find difference in execution.
Please note my cluster setup is on VirtualBox.
.set("deploy-mode", "client") or .set("deploy-mode", "cluster")
