   > Hi [@andygrove](https://github.com/andygrove) do you have a reproduce 
case, or at least a schema. `native-datafusion` reader should handle different 
kind of array/struct combintations
   
   This is the reason I was getting the error:
   
   ```scala
     private def isGloballySupported(dt: DataType): Boolean = dt match {
       case ByteType | ShortType
           if 
CometSparkSessionExtensions.usingDataFusionParquetExec(SQLConf.get) &&
             !CometConf.COMET_SCAN_ALLOW_INCOMPATIBLE.get() =>
         false
   ```
   
   Creating a struct or array containing byte or short should reproduce the 
issue.
