>
> With https://issues.apache.org/jira/browse/SPARK-51756 we have computed a 
> checksum for shuffle output which can be used to detect shuffle output 
> changes while retrying.
> Once ShuffleFetchFailed happens and checksum mismatch detected, we need to 
> retry the entire consumer stages since the producer stage generates different 
> data across different attempts.
> In this case, retrying the failed tasks for the consumer stages is not 
> sufficient, as the data may have been changed for other consumer tasks by the 
> non-deterministic producers.
