> Iceberg: Keep iceberg properties in sync with hms properties
> ------------------------------------------------------------
>
> Key: HIVE-27593
> URL: https://issues.apache.org/jira/browse/HIVE-27593
> Project: Hive
> Issue Type: Improvement
> Components: Iceberg integration
> Reporter: zhangbutao
> Assignee: zhangbutao
> Priority: Major
> Labels: pull-request-available
>
> In HIVE-26596, as we have not implement all COW mode, we enforced *mor* mode
> for iceberg v2 table in the tow scenarios:
> # create a v2 iceberg table, the delete mode will be set *mor* if not
> specified
> # upgrage v1 table to v2, and the delete mode will be set mor
>
> In HS2, we check the mode(cow/mor) from hms table properties instead of
> *iceberg* {*}properties(metadata json file){*}, and HIVE-26596 only change
> hms table properties. Therefore, it is ok for HS2 to operate iceberg table
> by checking cow/mor mode from hms properties, but for others like Spark, they
> operate the iceberg table by checking cow/mor from {*}iceberg
> properties(metadata json file){*}.
> Before we implement all COW mode, we need keep iceberg properties in sync
> with hms properties to make the users have the same experience on multiple
> engines(HS2 & Spark).
