Subject [jira] [Commented] (FLINK-7586) Report Watermark metrics in all operators
Date Wed, 06 Sep 2017 11:39:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-7586?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16155226#comment-16155226

Aljoscha Krettek commented on FLINK-7586:

True, but this issue is more general. We can update to old one to include all operators.

I think we should have this for 1.4 because debugging watermarks is very hard without this

>                 URL: https://issues.apache.org/jira/browse/FLINK-7586
>             Project: Flink
>          Issue Type: Bug
>          Components: DataStream API, Metrics
>    Affects Versions: 1.4.0, 1.3.2
>            Reporter: Aljoscha Krettek
>            Priority: Blocker
>             Fix For: 1.4.0
> Currently, the "currentLowWatermark" metric is only reported in {{StreamInputProcessor}}
(and the two-input version). This means that watermarks are only reported for operators directly
after a shuffle.
> We should report the watermark in all operators (including sources), so that users can
better diagnose problems with watermarks.
