> Impala should be able to read migrated partitioned Iceberg tables

> Key: IMPALA-11053
> URL: https://issues.apache.org/jira/browse/IMPALA-11053
> Project: IMPALA
> Issue Type: Bug
> Reporter: Zoltán Borók-Nagy
> Assignee: Zoltán Borók-Nagy
> Priority: Major
> Labels: impala-iceberg
> Fix For: Impala 4.1.0
>
>
> When Hive (and probably other engines as well) converts a legacy Hive table
> to Iceberg it doesn't rewrite the data files.
> It means that the data files don't have write ids, moreover they don't have
> the partition columns neither.
> Currently Impala expects tha partition columns to be present in the data
> files, so it won't be able to read converted partitioned tables.
> So we need to inject partition values from the Iceberg metadata, plus resolve
> columns correctly (position-based resolution needs an offset).
