Robert Metzger commented on FLINK-4034:
---------------------------------------

Hi, thank you for opening this issue.

We rely on the dependency version specified in Flink, not by transitive dependencies.
So in the case of Kryo, we rely on 2.24, for the zkclient, its 0.7.
I think that maven's dependency resolution is preferring the dependency versions specified by Flink over our transitive dependencies.

How do you plan to fix these issues?
