I think there are two major issues in this thread. The first is the API
problems. The second is the Hadoop 3 support. They are related, but I think
quickly dealing with the API issues can clarify what our options are for
Hadoop 3.
In the spirit of trying to keep these issues separate (I think
Christopher is correct)

If we switch to using the new shaded jars from Hadoop, we can avoid
coupling these issues at all. This comes with caveats as 3.0.0-beta1 is
busted (https://issues.apache.org/jira/browse/HADOOP-15058). Building a
3.0.1-SNAPSHOT locally and using that let me run all of the unit tests
which is promising.
Going to kick off the ITs and see how they fare.
