> Inconsistency in job shutdown produces confusing log message
> ------------------------------------------------------------

> Key: FLINK-9388
> URL: https://issues.apache.org/jira/browse/FLINK-9388
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Task
> Affects Versions: 1.5.0, 1.6.0
> Reporter: Stefan Richter
> Priority: Minor
> Labels: stale-minor
>
> I found some logged exceptions in a user log that occurred during shutdown in
> the context of latency markers. Those exceptions are most certainly not a
> real problem, but can be confusing to users, so maybe we can get rid of them.
