Thinking about this more, the change to a pom type instead of an empty jar is
better maven hygiene but means that downstream users who don't want to opt-in
to the shaded dependencies will have to update their dependency declaration for
the change.
i.e.
{code}
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-client</artifactId>
</dependency>
{code}
has to change to
{code}
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-client</artifactId>
<type>pom</type>
</dependency>
{code}
Is that what we want? On the positive side, it means downstream folks have to
think about wether they want to keep using the
client-with-third-party-dependencies or switch to the shaded client. On the
negative side, we are forcing all downstream users to think about things
instead of just those who are interested in the shaded client.

Happy to either clean up references to the non-pom dependency or change
hadoop-client back to an empty jar. Just need to know which a committer would
prefer.
(If I don't hear back one way or the other tonight, I'll decide which I think
is better and put up a patch + reasoning tomorrow.)

> As discussed in [HADOOP-11804 comment

> and following comments, there are still dependencies on the now-removed
> hadoop-client jar. The current code builds only because an obsolete snapshot
> of the jar is found on the repository server. Changing the project version
> to something new exposes the problem.
> While the build currently dies at hadoop-tools/hadoop-sls, I'm seeing issues
> with some Hadoop Client modules, too.
> I'm filing a new bug because I can't reopen HADOOP-11804.
