Arnab Karmakar updated IMPALA-15083:
------------------------------------
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).
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"`{}}} in
`{{{}IcebergSchemaConverter.toImpalaType()`{}}}.
Add read support by exposing UUID values as STRING in canonical RFC 4122 format
(`{{{}xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx`{}}}).
