------------------------------------------
Summary: Correct Iceberg type mappings
Key: IMPALA-10358
URL: https://issues.apache.org/jira/browse/IMPALA-10358
Project: IMPALA
Issue Type: Bug
Reporter: Zoltán Borók-Nagy
The Iceberg format spec defines what types to use for different type formats,
e.g.:
[https://iceberg.apache.org/spec/#parquet]
Impala should follow the specification:
* Strings in Iceberg tables should be annotated with UTF8 (when file format is
Parquet)
* Revise fixed(L) <-> CHAR(L) mapping
** CHAR(L) in Impala is annotated with UTF8
** fixed(L) is for fixed-length binary data
** We should probably remove this mapping
