Hi Ken,
Good point actually, thanks for pointing this out. In Flink project I see
that there is dependency on 2.24 and then I see transitive dependencies
through twitter.carbonite has a dependency on 2.21. Also, twitter.chill
that is used to manipulate Kryo as far as I understand, shows up with
versions 0.7.4 (Flink) and 0.3.5 (carbonite again). I wonder if this could
cause issues since if classes are not deduplicated class loading order
could be different on different machines. The maven project setup is fairly
complicated and I'm not a maven expert, so I would appreciate a second look
on that.
Thanks,
Timur
