peshopetrov commented on issue #20512: [SPARK-23182][CORE] Allow enabling TCP keep alive on the master RPC connections. URL: https://github.com/apache/spark/pull/20512#issuecomment-452470912 TCP keepalive will be disabled unless explicitly set per transport type. E.g.: ``` spark.rpc.io.enableTcpKeepAlive true spark.shuffle.io.enableTcpKeepAlive true ``` We actually set both, but if if only `spark.rpc.io.enableTcpKeepAlive` is set then it only applies for RPCs, or am I missing something?
