> Key: FLINK-6965
> URL: https://issues.apache.org/jira/browse/FLINK-6965
> Project: Flink
> Issue Type: Bug
> Components: Type Serialization System
> Affects Versions: 1.3.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Blocker
> Fix For: 1.3.2

>
> The shading rework made before 1.3 removed a snappy dependency that was accidentally pulled in through hadoop. This is technically alright, until class-loaders rear their ugly heads.
> Our kafka connector can read avro records, which may or may not require snappy. Usually this _should_ be solvable by including the snappy dependency in the user-jar if necessary, however since the kafka connector loads classes that it requires using the system class loader this doesn't work.
> As such we have to add a separate snappy dependency to flink-core.
