Saisai Shao commented on HIVE-16391:
------------------------------------
{quote}The problem with that is that it changes the meaning of Hive's
artifacts, so anybody currently importing hive-exec would see a breakage, and
that's probably not desired.
{quote}
This might not be acceptable from Hive community, because it will break the
current user as you mentioned.
As [~joshrosen] mentioned, Spark wants the hive-exec jar which shades kryo and
prototuf-java, not a pure non-shaded jar.
{quote}Another option is to change the artifact name of the current "hive-exec"
pom. Then you'd publish the normal jar under the new artifact name, then have a
separate module that imports that jar, shades dependencies, and publishes the
result as "hive-exec". That would maintain compatibility with existing
artifacts.

I can try this approach, but it seems not a small change for Hive, I'm not sure
if Hive community will accept such approach (at least for branch 1.2).

> Apache Spark currently depends on a forked version of Apache Hive. AFAIK, the
> only change in the fork is to work around the issue that Hive publishes only
> two sets of jars: one set with no dependency declared, and another with all
> the dependencies included in the published uber jar. That is to say, Hive
> doesn't publish a set of jars with the proper dependencies declared.
> There is general consensus on both sides that we should remove the forked
> Hive.
> The change in the forked version is recorded here
> https://github.com/JoshRosen/hive/tree/release-1.2.1-spark2
> Note that the fork in the past included other fixes but those have all become
> unnecessary.
