@jnturton Thanks for this. Aside from imports, which files were actually modified and I'll do a review?

Do we want to add this to back port to stable?

Yes, I'll split the import statement changes into a separate commit.

I don't think so. It's not a fix and it definitely carries a risk of breakage with it. Currently the Hadoop 2 build is broken because Drill's Guava patches (but not shading) are still needed in that case so I'll set the PR to draft for the moment.

@jnturton Is this PR still relevant?

@jnturton Is this PR still relevant?

Yes, I'm going to resurrect it after all the other clean up and upgrade PRs are in.
