-----------------------------------
Assignee: Tengfei Huang
> Computes order independent RowBasedChecksum in ShuffleWriters
> -------------------------------------------------------------
>
> Key: SPARK-54663
> URL: https://issues.apache.org/jira/browse/SPARK-54663
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 4.0.1
> Reporter: Tengfei Huang
> Assignee: Tengfei Huang
> Priority: Major
> Fix For: 4.1.0
>
>
> To help detect the shuffle output changes due to indeterminate stage retry,
> we need to introduce an order independent checksum for the shuffle output.
> Once the checksum changes, we'll know that this is from a indeterminate stage
> retry, will need to recompute all the succeeding stages for data correctness.
