Arnab Karmakar updated IMPALA-15200:
------------------------------------
Description:
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).
