Originally it was ORC when I created the table via Hive, but to make the 
Iceberg table usable in the tests I manually edit the JSON and AVRO metadata 
files. I think I created the metadata JSONs by copying from 
'iceberg_legacy_partition_schema_evolution' which is Parquet.

It didn't cause an issue because in functional_schema_template.sql we set the 
same table property in HMS to ORC.

But to be sure I also verified that the data files are ORC, by using the 'file' 
utility.
