Arnab Karmakar updated IMPALA-15200:
------------------------------------
Description: Read Parquet {{FIXED_LEN_BYTE_ARRAY(16)}} UUID columns into
inline 16-byte slots; add basic {{SELECT}} query tests. (was: 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" from IcebergSchemaConverter#toImpalaType.
Add read support by exposing UUID values as STRING in canonical RFC 4122 format
(xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).
)
