Subject [jira] [Commented] (FLINK-14470) Watermark display not working with high parallelism job
Date Mon, 21 Oct 2019 03:02:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-14470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16955715#comment-16955715

Thomas Weise commented on FLINK-14470:
--------------------------------------

I'm actually not sure hiding is desirable. As it stands the user will at least notice there
is something wrong with the UI whereas before the an issue with the job was the first assumption.

> 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.
