------------------------------------------
Summary: Impala cannot resolve columns of converted Iceberg table
Key: IMPALA-10974
URL: https://issues.apache.org/jira/browse/IMPALA-10974
Project: IMPALA
Issue Type: Bug
Reporter: Zoltán Borók-Nagy
When a regular Parquet/ORC table is converted to Iceberg via Hive, only the
Iceberg metadata files need to be created. The data files can stay in place.
This causes problems when the data files don't have field ids for the schema
elements. Currently Impala resolves columns in data files based on Iceberg
field ids, but since they are missing, Impala raises an error or returns NULLs.
We could fallback to the default column resolution strategy when the data files
lack field ids.
