------------------------------------
Thanks [~uce] for catching this, I should have tested this feature more
thoroughly

> Key: FLINK-14145
> URL: https://issues.apache.org/jira/browse/FLINK-14145
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.9.0
> Reporter: Ufuk Celebi
> Assignee: Gyula Fora
> Priority: Major
> Labels: pull-request-available
> Attachments:
> 0001-FLINK-14145-runtime-Add-getLatestCheckpoint-test.patch
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The flag to prefer checkpoints for recovery introduced in FLINK-11159 returns
> the wrong checkpoint if:
> * checkpoints are preferred ({{getLatestCheckpoint(true)}}),
> * the latest checkpoint is *not* a savepoint,
> * more than a single checkpoint is retained.
> The current implementation assumes that the latest checkpoint is a savepoint
> and skips over it. I attached a patch for
> {{StandaloneCompletedCheckpointStoreTest}} that demonstrates the issue.
> You can apply the patch via {{git am -3 < *.patch}}.
