---------------------------------
Hi [~ibzib] very thanks for reporting the issue! What flink version is the test
running towards ?
> Precondition failed building CheckpointMetrics.

> Key: FLINK-23302
> URL: https://issues.apache.org/jira/browse/FLINK-23302
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Reporter: Kyle Weaver
> Priority: Major
>
> Beam has a flaky test using Flink savepoints. It looks like
> alignmentDurationNanos is less than -1, which shouldn't be possible. As far
> as I know clients (like Beam) don't have any control over this value, so my
> best guess is that it's a bug in Flink.

> for context.
> The failing test is here:
