I've not got a good notion right now of how heavy our dependency is on Guava
(although I know I have increased it myself by using it various places!)
Does it seem (for the long term) worth investigating the possibilities of
moving off Guava entirely?
Is it more nuanced than that? I have been using Guava's caching whenever
I need a cache. There are other possibilities. (Commons JCS,
commons-collections4#map.LRUMap
Can we agree on what we consider the base dependencies (commons-lang3,
commons-io, commons-codec etc)?

Yes that would be a good idea
You should just be able to change a single property and see if it Will compile.
See the instructions on the website:

So for next steps, should someone (aka me) try to build against a 3.X Hadoop
to see where the jolts are? Does that make sense as a way to gather more info?
I would just go ahead and do it, but lacking (as I do) any Hadoop dev
experience, I want to make sure that it's a good idea before investing time.

My impression is that 3.0 is still a long way off a generally available release
since they are still in Alpha at the moment.
I would expect that 2.x would remain the primary distribution for a while yet.
I don’t know how much, If at all, map/reduce has changed so it may already be
possible to build Elephas against 3.X without any changes but then again it
might not.
I’m not sure that it is necessarily safe to stop shading Guava. It is a widely
used library with poor compatibility between versions and our users may
experience Version conflicts in other environments.

I would think the same. Unless we have other important features to be
released, maybe something that breaks backward compatibility, etc.

Maybe we can see what Hadoop itself ends up doing for this problem... they
are targeting their own major release 3 for this. I would think we could go
with a minor version for this, no? Or is Elephas such a big part of our
offering that we need to make a major release to move with Hadoop...?

Step 1: upgrade jena-shaded-guava to v21.0
and see if it works.
There are at least two considerations:
* Jena would have to move in step with Hadoop
and drop support for older versions.
* Our downstream users may have guava version choices.
and we have to wait until a Hadoop release to remove it.

Looks like Hadoop has successfully updated their Guava dependency-- this might
provide us the opportunity to stop shading Guava. (yay!)

update the version to as latest version as possible.
