-----------------------------
Summary: RocksDBKeyedStateBackend uses incorrect key serializer if
reconfigure happens during restore
Key: FLINK-12064
URL: https://issues.apache.org/jira/browse/FLINK-12064
Project: Flink
Issue Type: Bug
Reporter: Yu Li
Assignee: Yu Li
Fix For: 1.8.0
As titled, in current {{RocksDBKeyedStateBackend}} we use {{keySerializer}}
rather than {{keySerializerProvider.currentSchemaSerializer()}}, which is
incorrect. The issue is not revealed in existing UT since current cases didn't
check snapshot after state schema migration.
This is a regression issue caused by the FLINK-10043 refactoring work.
