Rui Fan created FLINK-31959:
-------------------------------

             Summary: Correct the unaligned checkpoint type at checkpoint level
                 Key: FLINK-31959
                 URL: https://issues.apache.org/jira/browse/FLINK-31959
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Checkpointing
    Affects Versions: 1.16.1, 1.17.0, 1.18.0
            Reporter: Rui Fan
            Assignee: Rui Fan


FLINK-18851 added the checkpoint type in web UI to distinguish aligned checkpoint, unaligned checkpoint, savepoint and savepoint on cancel in {*}Flink 1.12{*}.

It distinguishes between UC and AC based on whether UC is enabled or disabled.[1]

However, FLINK-19680, FLINK-19681 and FLINK-19682 introduced the alignment-timeout in {*}Flink 1.13{*}, and it has been changed to {{aligned-checkpoint-timeout.}}
{code:java}
When activated, each checkpoint will still begin as an aligned checkpoint, but when the global checkpoint duration exceeds the aligned-checkpoint-timeout, if the aligned checkpoint has not completed, then the checkpoint will proceed as an unaligned checkpoint.{code}
If UC and AC-timeout is enabled and the checkpoint is completed as aligned checkpoint. It should show the unaligned checkpoint instead of aligned checkpoint.
