The previous check only rejected top-level MapType grouping expressions. This caused a CometNativeException crash when grouping by ARRAY(MAP(...)) because Comet native cannot handle 'Row format support not yet implemented for List(Map(...))'. Fix by recursively checking for MapType within ArrayType and StructType. This ensures we correctly fall back to Spark for any grouping expression that contains a MapType at any nesting level. -- This is an automated message from the Apache Git Service.
