>             Project: Flink
>          Issue Type: Bug
>          Components: Runtime / Web Frontend
>    Affects Versions: 1.8.2, 1.9.1
>            Reporter: Thomas Weise
>            Assignee: Yadong Xie
>            Priority: Major
> Watermarks don't display in the UI when the job graph has many vertices. The REST API
call to fetch currentInputWatermark fails as it enumerates each subtask, which obviously fails
beyond a limit. With the new UI that can be noticed through a flickering error message in
the upper right corner.
