[jira] [Created] (FLINK-6805) Flink Cassandra connector dependency
on Netty disagrees with Flink
Shannon Carey created FLINK-6805:
------------------------------------
Summary: Flink Cassandra connector dependency on Netty disagrees with Flink
Key: FLINK-6805
URL: https://issues.apache.org/jira/browse/FLINK-6805
Project: Flink
Issue Type: Bug
Components: Cassandra Connector
Affects Versions: 1.2.1, 1.3.0
Reporter: Shannon Carey
The Flink Cassandra connector has a dependency on Netty libraries (via promotion of transitive dependencies by the Maven shade plugin) at version 4.0.33.Final, which disagrees with the version included in Flink of 4.0.27.Final which is included & managed by the parent POM via dependency on netty-all.
Due to use of netty-all, the dependency management doesn't take effect on the individual libraries such as netty-handler, netty-codec, etc.
I suggest that dependency management of Netty should be added for all Netty libraries individually (netty-handler, etc.) so that all Flink modules use the same version, and similarly I suggest that exclusions be added to the quickstart example POM for the individual Netty libraries so that fat JARs don't include conflicting versions of Netty.
