URL: https://github.com/apache/arrow-datafusion/issues/2439

   I have a parquet file with schema of nested array. There are several levels 
where type is array but data is empty. When use this data with datafusion I am 
getting this error:
   
   ```
   ArrowError(ComputeError("concat requires input of at least one array"))
   ```
   
   Even if use projection with only non nested columns then also I am getting 
the above error. Can you someone share thoughts on how can I get away with this 
error?
