-------------------------------------
[~pan3793] / [~csun] Can you let me know what all dependencies are creating
problem for Spark or the projects you folks flagged.
I think most of the shaded dependencies can be relocated, I don't think that
would be a problem, excluding couple of them like calcite.
I can give it a try and see if things work for these projects, so we can try
the hive-master version with these projects and if no other blocker, can
attempt an upgrade there

> Key: HIVE-26220
> URL: https://issues.apache.org/jira/browse/HIVE-26220
> Project: Hive
> Issue Type: Improvement
> Affects Versions: 4.0.0
> Reporter: Chao Sun
> Priority: Blocker
>
> Currently projects like Spark, Trino/Presto, Iceberg, etc, are depending on
> {{hive-exec:core}} which was removed in HIVE-25531. The reason these projects
> use {{hive-exec:core}} is because they have the flexibility to exclude, shade
> & relocate dependencies in {{hive-exec}} that conflict with the ones they
> brought in by themselves. However, with {{hive-exec}} this is no longer
> possible, since it is a fat jar that shade those dependencies but do not
> relocate many of them.
> In order for the downstream projects to consume {{hive-exec}}, we will need
> to make sure all the dependencies in {{hive-exec}} are properly shaded and
> relocated, so they won't cause conflicts with those from the downstream.
