Apache Spark reassigned SPARK-42689:
------------------------------------
Assignee: Apache Spark
> Allow ShuffleDriverComponent to declare if shuffle data is reliably stored
> --------------------------------------------------------------------------
>
> Key: SPARK-42689
> URL: https://issues.apache.org/jira/browse/SPARK-42689
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 3.1.0, 3.2.0, 3.3.0, 3.4.0
> Reporter: Mridul Muralidharan
> Assignee: Apache Spark
> Priority: Major
>
> 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].
