yuchenhuo commented on issue #26614: [SPARK-29976] New conf for single task stage speculation URL: https://github.com/apache/spark/pull/26614#issuecomment-557740547 @squito Good point! If I understand correctly, the better way to do this is to have a flag like `spark.speculation.aggressive` and maybe check the executed time of all the running tasks and if it exceeds the threshold, then speculative run the task. Do you think it necessary to additionally check if the tasks are running on the same executor and only speculate if so?
