> Noisy logs from metric fetcher
> ------------------------------
>
> Key: FLINK-6440
> URL: https://issues.apache.org/jira/browse/FLINK-6440
> Project: Flink
> Issue Type: Bug
> Components: Webfrontend
> Affects Versions: 1.3.0
> Reporter: Stephan Ewen
> Assignee: Chesnay Schepler
> Priority: Critical
> Fix For: 1.3.0
>
>
> In cases where TaskManagers fail, the web frontend in the Job Manager starts
> logging the exception below every few seconds.
> I labeled this as critical, because it actually makes debugging in such a
> situation complicated through a log that is flooded with noise.
