tgravescs commented on issue #27240: [SPARK-30512] Added a dedicated boss event loop group URL: https://github.com/apache/spark/pull/27240#issuecomment-577850213 interesting, I had asked about the Boss thread a long time back and must not have understood it properly at the time. So is the Boss thread handling the actual bootstrap for authentication before handing off to the worker threads? Our is the boss thread just accepted the connection and then queueing them to be processed by the worker? Can you please give more detail on exactly how this fixes it and what threads are doing what in the Spark case. Also with this change we should actually be able to remove the change from SPARK-24355 then, correct?
