--------------------------------------
I think you are right [~sihuazhou] that this issue is kind of a duplicate of
FLINK-9215. Closing the issue now.
> Reduce noisiness of SlotPool logging
> ------------------------------------
>
> Key: FLINK-9277
> URL: https://issues.apache.org/jira/browse/FLINK-9277
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.5.0
> Reporter: Stephan Ewen
> Assignee: Till Rohrmann
> Priority: Critical
>
> The slot pool logs a vary large amount of stack traces with meaningless
> exceptions like {code}
> org.apache.flink.util.FlinkException: Release multi task slot because all
> children have been released.
> {code}
> This makes log parsing very hard.
> For an example, see this log:
