-----------------------------------

             Summary: 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


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.

See 
https://issues.apache.org/jira/browse/BEAM-10955?focusedCommentId=17376928&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17376928
 for context.

The failing test is here:
