> Key: IMPALA-11595
> URL: https://issues.apache.org/jira/browse/IMPALA-11595
> Project: IMPALA
> Issue Type: Bug
> Reporter: Noemi Pap-Takacs
> Assignee: Noemi Pap-Takacs
> Priority: Minor
>
> File format in case of Iceberg tables can be defined with tblproperty
> 'write.format.default'. This used to be set by 'iceberg.file_format' which is
> still supported for backward compatibility. It should implement the same
> functionality. However, this is not the case. Currently, anything can be set
> with 'iceberg.file_format' , but the files will be stored in Parquet
> regardless of what the user set. Even if the given file format is supported,
> the fallback to the default Parquet is done without any feedback, and there
> is no error message either, when the chosen file format is not supported.
> Impala should support 'iceberg.file.format' property to do exactly what
> 'write.format.default' does.
