1996fanrui opened a new pull request, #23873: URL: https://github.com/apache/flink/pull/23873
## What is the purpose of the change When the default value of Duration is 24 hours or 1 day, the display unit is ms. (86400000 ms). For example, the [kubernetes operator doc](https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-main/docs/operations/configuration/) has 3 options, their default value are 86400000 ms. This bug from `org.apache.flink.util.TimeUtils#formatWithHighestUnit`, and it can be reproduced by `TimeUtilsPrettyPrintingTest`. Bug reason: When the duration is `1 day`, it filters all TimeUnits, so it uses the default `TimeUnit.MILLISECONDS`. <img width="1065" alt="image" src="https://github.com/apache/flink/assets/38427477/42696e58-e147-45d3-b93f-cafa9ae6ec8e"> ## Brief change log - [FLINK-33752][Configuration] Change the displayed timeunit to day when the duration is an integral multiple of 1 day - Find the correct `HighestIntegerUnit` for 1day. ## Verifying this change - Added some arguments for `TimeUtilsPrettyPrintingTest#testFormatting` ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: no - The serializers: no - The runtime per-record code paths (performance sensitive): no - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: no - The S3 file system connector: no ## Documentation - Does this pull request introduce a new feature? no - If yes, how is the feature documented?
