[jira] [Created] (FLINK-23831) Verify the final checkpoint and stop-with-savepoint --drain

Yun Gao created FLINK-23831:
-------------------------------

             Summary: Verify the final checkpoint and stop-with-savepoint --drain
                 Key: FLINK-23831
                 URL: https://issues.apache.org/jira/browse/FLINK-23831
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Checkpointing
    Affects Versions: 1.14.0
            Reporter: Yun Gao
             Fix For: 1.14.0


In 1.14 we support checkpoints with part of tasks finished, and based on this functionality, we further support the final checkpoint and unify the process of stop-with-savepoint --drain. 

In order to test the new feature, we may need to verify:
1. Checkpoint with the finished tasks.
2. Restore from the checkpoint with finished tasks.
3. All the data are committed correctly for bounded jobs with 2pc sinks.
4. Stop-with-savepoint --drain remains correct.
5. All the above tests also work with unaligned checkpoint.
