> When Impala creates an Iceberg table it sets HMS table property 'iceberg.file_format' to indicate the underlying data file format.
> However, when the table was created by Hive or Spark, we don't have this property and Impala assumes that the data file format is PARQUET. This assumption is just a wild guess, and when it's wrong Impala raises an error during query execution.
> Instead of only checking the table property, Impala could also try to determine the file format based on Iceberg metadata.
