Hi, In case we run Spark on Yarn in client mode, we have firewall for Hadoop cluster, and the client node is outside firewall, I think I have to open some ports that Application Master uses.
I think the ports is specified by "spark.yarn.am.port" as document says. https://spark.apache.org/docs/latest/running-on-yarn.html But, according to the source code, spark.yarn.am.port is deprecated since 2.0. https://github.com/apache/spark/commit/829cd7b8b70e65a91aa66e6d626bd45f18e0ad97 Does this mean we do not need to open particular ports of firewall for Spark on Yarn? Thanks,
