coderplay edited a comment 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-452178010 Clarification: I am not a spark expert, just got an invitation from @rxin because he think I have some knowledge about linux TCP. Generally, the patch looks good to me for the purpose of preventing inactivity from disconnecting the channel. But from the diff, looks like this commit will impact other RPCs or shuffling transport as well. It's not only for master RPCs as the title declared. Min
