> Currently, if there is an executor node loss, we assume the shuffle data on that node is also lost. This is not necessarily the case if there is a shuffle component managing the shuffle data and reliably maintaining it (for example, in distributed filesystem or in a disaggregated shuffle cluster).
> Downstream projects have patches to Apache Spark in order to workaround this issue, for example Apache Celeborn has [this|https://github.com/apache/incubator-celeborn/blob/main/assets/spark-patch/RSS_RDA_spark3.patch].
