> Right now Hive-3 only supports MR execution engine for its DML operations.
> MR is almost obsolete and majority of the users use Tez execution engine for
> their Hive jobs.
> Most of the components needed for Tez to support Iceberg tables are available
> in MR and can be reused.
> Few Tez related fixes which were done in Hive-4 had to be ported:

> to happen in Iceberg.
