--------------------------------------
> Operator state backend should set user classloader as context classloader

> Key: FLINK-6714
> URL: https://issues.apache.org/jira/browse/FLINK-6714
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
> Priority: Blocker
> Fix For: 1.3.0, 1.4.0
>
>
> Now that the operator state backend creates a deep copy of the state during
> the synchronous part of async checkpoints, it needs to set the user
> classloader as the thread context classloader, otherwise serializers that
> uses serialization for copying will use the wrong classloader when
> deserializing the copy.
