Summary: Operator state backend should set user classloader as context classloader when snapshotting 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 Now that the operator state backend creates a deep copy of the state during the synchronous part of 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
