-------------------------------

             Summary: Handle fallback when merged shuffle blocks are corrupted and spark.shuffle.detectCorrupt is set to true
                 Key: SPARK-38987
                 URL: https://issues.apache.org/jira/browse/SPARK-38987
             Project: Spark
          Issue Type: Sub-task
          Components: Shuffle
    Affects Versions: 3.2.0
            Reporter: Ye Zhou


Current implementation doesn't handle the corruption cases well for merged shuffle blocks, and if there is a corrupted shuffle chunk, the task will directly fail with the error message shown below, without triggering the expected fallback, which will try fetching original unmerged shuffle blocks:
org.apache.spark.SparkException: Failed to get block shuffleChunk_30_0_1070_0, which is not a shuffle block
