> Several SerDe and UDF jars tend to shade in various parts of the dependencies
> including hadoop-common or guava without relocation.
> Implement a simple udflint tool which automates some part of the class path
> and shaded resources audit process required when upgrading a hive install
> from an old version to a new one.
