[jira] [Created] (SPARK-34899) Use origin plan if can not coalesce shuffle partition

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

             Summary: Use origin plan if can not coalesce shuffle partition
                 Key: SPARK-34899
                 URL: https://issues.apache.org/jira/browse/SPARK-34899
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: ulysses you


The `CoalesceShufflePartitions` can not coalesce such case if the total shuffle partitions of mappers are big enough. Then it's confused to use `CustomShuffleReaderExec` which marked as `coalesced` but has no affect with partition number.
