Not able to convert parquet to iceberg format

Hi Team,

I have a dremio instance that connects to Azure storage datasource. I am trying to convert the parquet files in the Azure blob storage to iceberg format in dremio. I have already set the “iceberg.enabled” and “iceberg.ctas.enabled” flags to true. I am getting the attached error while manually converting the file format to iceberg. Please let me know if I missed any settings.


UI that you are using is not for conversion but rather for promotion of an existing Iceberg table.
What’s your end goal here? Querying parquet files? Or storing existing data in Iceberg format?

If first - promote as Parquet from same UI and query.
If second - promote as Parquet and then use CTAS as shown in example here
