Vladislav Pernin commented on FLINK-4034:
-----------------------------------------
[~rmetzger] In case of "dependency divergence", I have to make a decision:
- always sticking to the current resolved version, which would garanty zero
regression, but leave us with some differents libraires version choices among
the Flink modules, and a complicated dependencyManagement/exclusions
- always upgrading to the biggest version (not the latest library version
published but in a conflict between two versions, choosing the latest), has
some possible impact
- a mixed strategy depending of the libraries
Are we confident enough in the unit test ?
What do you think ?

> Reporter: Vladislav Pernin
>
> If dependency convergence is enabled and asserted on Maven, projects using
> Flink do not compile.
> Example :
> {code}
> Dependency convergence error for com.esotericsoftware.kryo:kryo:2.24.0 paths
> to dependency are:
> +-groupidXXX:artifactidXXX:versionXXX
> +-org.apache.flink:flink-java:1.0.3
> +-org.apache.flink:flink-core:1.0.3
> +-com.esotericsoftware.kryo:kryo:2.24.0
> and
> +-groupidXXX:artifactidXXX:versionXXX
> +-org.apache.flink:flink-streaming-java_2.11:1.0.3
> +-org.apache.flink:flink-runtime_2.11:1.0.3
> +-com.twitter:chill_2.11:0.7.4

> {code}
> Dependency convergence error for com.101tec:zkclient:0.7 paths to dependency
> are:
> +-groupidXXX:artifactidXXX:versionXXX
> +-org.apache.flink:flink-connector-kafka-0.8_2.11:1.0.3
> +-org.apache.flink:flink-connector-kafka-base_2.11:1.0.3
