zsxwing commented on issue #24796: [SPARK-27900][CORE] Add uncaught exception handler to the driver URL: https://github.com/apache/spark/pull/24796#issuecomment-499764530 > `onReceive()` is interrupted before `onStop()` But there will be a race condition if removing `join`. We cannot guarantee that `onReceive` can return immediately when it receives the interrupt signal. By the way, is there any theory about how this deadlock can happen? As I mentioned here: https://github.com/apache/spark/pull/24796#discussion_r290908122 I could not reproduce it.
