问题
I am currently using Spark on AWS EMR, but when this is behind a Load Balancer (AWS ELB), it is redirecting the traffic from https to http, which then ends up getting denied because I don't allow http traffic through the load balancer for the given port. It appears that this might derive from Yarn being a proxy as well, but I have no idea.
