cloud-fan commented on issue #26975: [SPARK-30325][CORE] Stage retry and executor crash cause app hung up forever URL: https://github.com/apache/spark/pull/26975#issuecomment-568682889 I don't think it's safe to not reschedule it. Looking at the comment in `executorLost`, we want to reschedule because the shuffle files are all lost in this executor. The special case is `killedByOtherAttempt.contains(tid)`, which means a speculative task has finished on **another executor**. For the stage attempt, there is no guarantee that 2 tasks of the same partition will be run on different executors.
