> Key: FLINK-31959
> URL: https://issues.apache.org/jira/browse/FLINK-31959
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.17.0, 1.16.1, 1.18.0
> Reporter: Rui Fan
> Assignee: Rui Fan
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.16.2, 1.18.0, 1.17.1

>
> 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 aligned checkpoint instead of unaligned
> checkpoint.
