Jacques Nadeau commented on ARROW-1864:
---------------------------------------
Probably only a moderate amount of work. It's possible they made some things
private that could cause problems but I'm not aware of anything offhand.
I probably can't get to it in the next week or two. If someone else wants to
pick it up, switch the pom and the identify the issues I'd be to try to help
give guidance on how to address any issues found.

>
> The Netty community will declare Netty 4.0.x as EOL at the beginning of the
> second quarter of 2018: https://github.com/netty/netty/issues/7439
> It would be great that Arrow can migrate to Netty 4.1.x soon. This is the
> only blocker for Spark to migrate to Netty 4.1.x.
