             Summary: "Failure to finalize checkpoint" error in MasterTriggerRestoreHook
                 Key: FLINK-18641
                 URL: https://issues.apache.org/jira/browse/FLINK-18641
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Checkpointing
    Affects Versions: 1.11.0
            Reporter: Brian Zhou


https://github.com/pravega/flink-connectors is a Pravega connector for Flink. The ReaderCheckpointHook[1] class uses the Flink `MasterTriggerRestoreHook` interface to trigger the Pravega checkpoint during Flink checkpoints to make sure the data recovery. The checkpoint recovery tests are running fine in Flink 1.10, but it has below issues in Flink 1.11 causing the tests time out.
