Hi Spark list, I'm looking to apply some iptables firewall rules to my spark cluster and am not entirely sure what ports are required. I didn't see any specific documentation of what ports Spark requires, so compiled this (incomplete) list.
*From* *To* *Port (default)* *Purpose* admin machine master 8080 master webui admin machine worker 8081 worker webui admin machine application 4040application webuiworkermaster7077join clusterworkerworker?shuffle datamasterworker?schedule jobs Can someone help me out with the last couple ports and fill in any other entries that might be missing? Thanks! Andrew
