Summary: Make it possible to drop an old unused registered Kryo serializer Key: FLINK-26960 URL: https://issues.apache.org/jira/browse/FLINK-26960 Project: Flink Issue Type: Bug Components: API / Type Serialization System Affects Versions: 1.14.4, 1.13.6, 1.12.7, 1.15.0 Reporter: Dawid Wysakowicz If users register a Kryo serializer e.g. via: {code} env.registerTypeWithKryoSerializer(ClassA. ClassASerializer.class); {code} and then use a Kryo serializer for serializing state objects, the registered serializer is written into the KryoSerializer snapshot. Even if Kryo is used for serializing classes other than ClassA. This makes it impossible to remove {{ClassASerializer}} from the classpath, because it is required for reading the savepoint. -- This message was sent by Atlassian Jira (v8.20.1#820001)
