xuanyuanking edited a comment on issue #25420: [SPARK-28699][Core] Cache an indeterminate RDD could lead to incorrect result while stage rerun URL: https://github.com/apache/spark/pull/25420#issuecomment-522481100 Sorry for the late. Thanks for the comment and review! After taking a further investigation, I found the root cause for this issue is about radix sort in ShuffleExchangeExec, please review it in #25491. The bug fix of DAGScheduler is still needed, I'll give another follow-up PR and add UT for it. Done in #25498.
