> ---------------------------------------
>
> Key: IMPALA-15083
> URL: https://issues.apache.org/jira/browse/IMPALA-15083
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend, Frontend
> Reporter: Arnab Karmakar

> Priority: Major
> Labels: impala-iceberg
>
> Iceberg's UUID type is stored as `{{{}FIXED_LEN_BYTE_ARRAY(16)`{}}} in
> Parquet with a UUID logical type annotation. Currently Impala throws
> `{{{}"Iceberg type 'UUID' is not supported in Impala"`{}}} in
> `{{{}IcebergSchemaConverter.toImpalaType()`{}}}.
> Add read support by exposing UUID values as STRING in canonical RFC 4122
> format (`{{{}xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`{}}}).
