viirya opened a new issue, #943: URL: https://github.com/apache/datafusion-comet/issues/943
### Describe the bug Because CometShuffleExchangeExec as a Spark operator supports columnar execution, Spark will add RowToColumnar between it and its child operator which produces row-based output. But CometShuffleExchangeExec for columnar shuffle will call `execute` on its child operator, it is actually a RowToColumnarTransition and the RowToColumnar is redundant. ### Steps to reproduce _No response_ ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
