---------------------------------------------
Do we want to add a documentation task for this jira as well [~Ngone51] ?
> Add checksum for shuffle blocks
> -------------------------------
>
> Key: SPARK-35275
> URL: https://issues.apache.org/jira/browse/SPARK-35275
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 3.2.0
> Reporter: wuyi
> Priority: Major
>
> Shuffle data corruption is a long-standing issue in Spark. For example, in
> SPARK-18105, people continually reports corruption issue. However, data
> corruption is difficult to reproduce in most cases and even harder to tell
> the root cause. We don't know if it's a Spark issue or not. With the checksum
> support for the shuffle, Spark itself can at least distinguish the cause
> between disk and network, which is very important for users.
