Sean Busbey commented on HADOOP-11804:
--------------------------------------
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.
