Description

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.
