[jira] [Created] (FLINK-9328) RocksDBStateBackend might use PlaceholderStreamStateHandle to restor due to StateBackendTestBase class not register snapshots in some UTs

Yun Tang created FLINK-9328:
-------------------------------

             Summary: RocksDBStateBackend might use PlaceholderStreamStateHandle to restor due to StateBackendTestBase class not register snapshots in some UTs
                 Key: FLINK-9328
                 URL: https://issues.apache.org/jira/browse/FLINK-9328
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing
    Affects Versions: 1.4.2
            Reporter: Yun Tang
             Fix For: 1.5.0


Currently, StateBackendTestBase class does not register snapshots to SharedStateRegistry in testValueState, testListState, testReducingState, testFoldingState and testMapState UTs, which may cause RocksDBStateBackend to restore from PlaceholderStreamStateHandle during the 2nd restore procedure if one specific sst file both existed in the 1st snapshot and the 2nd snapshot handle.
