> HIVE4 can't use ICEBERG table in subqueries
> -------------------------------------------
>
> Key: HIVE-27898
> URL: https://issues.apache.org/jira/browse/HIVE-27898
> Project: Hive
> Issue Type: Improvement
> Components: Iceberg integration
> Affects Versions: 4.0.0-beta-1
> Reporter: yongzhi.shao
> Priority: Critical
>
> Currently, we found that when using HIVE4-BETA1 version, if we use ICEBERG
> table in the subquery, we can't get any data in the end.
> I have used HIVE3-TEZ for cross validation and HIVE3 does not have this
> problem when querying ICEBERG.
