> Duplicating a KryoSerializer does not duplicate registered default serializers
> ------------------------------------------------------------------------------
>
> Key: FLINK-8836
> URL: https://issues.apache.org/jira/browse/FLINK-8836
> Project: Flink
> Issue Type: Bug
> Components: Type Serialization System
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Stefan Richter
> Priority: Blocker
> Fix For: 1.5.0
>
>
> The {{duplicate()}} method of the {{KryoSerializer}} is as following:
> {code:java}
> public KryoSerializer<T> duplicate() {
> return new KryoSerializer<>(this);
> }
> protected KryoSerializer(KryoSerializer<T> toCopy) {
> defaultSerializers = toCopy.defaultSerializers;
> defaultSerializerClasses = toCopy.defaultSerializerClasses;
> kryoRegistrations = toCopy.kryoRegistrations;
> ...
> }
> {code}
> Shortly put, when duplicating a {{KryoSerializer}}, the
> {{defaultSerializers}} serializer instances are directly provided to the new
> {{KryoSerializer}} instance.
> This causes the fact that those default serializers are shared across two
> different {{KryoSerializer}} instances, and therefore not a correct duplicate.
