Jakob Homan commented on HIVE-3017:
-----------------------------------
Something this bad should be fixed. It's particularly vexing when trying to
develop against Hive and needing to update two jars for one class. Fat-jarring
(which this esesentially is) is evil. If the intention is to provide a
convenient package for deployment, can't that be done in maven by declaring a
meta project with the other jars?

> Was this intentional? If so, the serde jar should be deprecated. If not, the
> serde classes should be removed since this creates two sources of truth for
> them and can cause other problems (see HCATALOG-407).
