Description

Currently we prohibit setting the following properties:

• iceberg.catalog
• iceberg.catalog_location
• iceberg.file_format
• icceberg.table_identifier

Impala needs these properties to be able to correctly use the table. However, if the table was created by an other engine. e.g. by Hive, then the table won't have these properties.

We need to allow setting at least 'iceberg.file_format'.
