> Iceberg allows having different file formats in a single table. It stores the file format information for each data file.
> Impala only allows a single file format per partition. Iceberg tables are handled as non-partitioned HMS tables (Iceberg partitioning is more or less hidden from Impala). Therefore currently Impala don't allow having different file formats in a single table.
