> Key: FLINK-33429
> URL: https://issues.apache.org/jira/browse/FLINK-33429
> Project: Flink
> Issue Type: Bug
> Components: Autoscaler
> Affects Versions: kubernetes-operator-1.7.0
> Reporter: Maximilian Michels
> Assignee: Maximilian Michels
> Priority: Minor
> Labels: pull-request-available
> Fix For: kubernetes-operator-1.7.0
>
>
> The new code for the 1.7.0 release introduces metric collection during the
> stabilization phase to allow sampling the observed true processing rate.
> Metrics might not be fully initialized during that phase, as evident through
> the error metrics. The following error is thrown:
> {noformat}
> java.lang.RuntimeException: Could not find required metric
> NUM_RECORDS_OUT_PER_SEC for 667f5d5aa757fb217b92c06f0f5d2bf2
> {noformat}
> To prevent these errors shadowing actual errors, we should detect and ignore
> this recoverable exception.
