> --------------------------------------------------------------------------------------------
>
> Key: FLINK-32535
> URL: https://issues.apache.org/jira/browse/FLINK-32535
> Project: Flink
> Issue Type: Bug
> Components: Runtime / REST
> Affects Versions: 2.1.0
> Reporter: Hong Liang Teoh
> Priority: Major
> Fix For: 2.1.0
>
>
> *What*
> When making requests to /checkpoints REST API after a job restart, we see 500
> for a short period of time. We should handle this gracefully in the
> CheckpointingStatisticsHandler.
>
> *How to replicate*
> * Checkpointing interval 1s
> * Job is constantly restarting
> * Make constant requests to /checkpoints REST API.
> See [here|https://github.com/apache/flink/pull/22901#issuecomment-1617830035]
