-----------------------------------------
Summary: Support Iceberg file format property correctly for
backward compatibility
Key: IMPALA-11595
URL: https://issues.apache.org/jira/browse/IMPALA-11595
Project: IMPALA
Issue Type: Bug
Reporter: Noemi Pap-Takacs
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.
