Description

The check on alignmentDurationNanos seems to be too strict at the line:
https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/checkpoint/CheckpointMetrics.java#L74

This caused a job to fail when doing stop-with-savepoint. But doing savepoint only without stop does not seem to be impacted by this.
