Seth Wiesman updated FLINK-19999:
---------------------------------
Affects Version/s: 1.12.0
> State Processor API classes leaking into savepoint
> --------------------------------------------------
>
> Key: FLINK-19999
> URL: https://issues.apache.org/jira/browse/FLINK-19999
> Project: Flink
> Issue Type: Bug
> Components: API / State Processor
> Affects Versions: 1.12.0, 1.11.2
> Reporter: Nico Kruber
> Priority: Major
>
> Currently, any configuration for serializers that you are using when writing
> a State Processor API job will be shared with the serializers that are used
> for writing a savepoint. However, your normal job shouldn't necessarily
> depend on (helper) classes that you only use in the StateProc API job.
> By default, for example, {{ExecutionConfig#autoTypeRegistrationEnabled =
> true}} and thus classes like
> {{org.apache.flink.runtime.checkpoint.OperatorSubtaskState}} will be
> registered with Kryo and will thus also be needed when reading the created
> savepoint if you have Kryo serialization in your job.
> This particular instance can be worked around by calling
> {{ExecutionConfig#disableAutoTypeRegistration()}} but the problem is probably
> bigger and extends to other type registrations, e.g. POJOs, as well.
