> Key: FLINK-39890
> URL: https://issues.apache.org/jira/browse/FLINK-39890
> Project: Flink
> Issue Type: Bug
> Components: Kubernetes Operator
> Affects Versions: 1.12.0, 1.13.0, 1.14.0, 1.15.0
> Reporter: lrsb
> Priority: Minor
> Labels: pull-request-available
>
> With job.autoscaler.observed-scalability.enabled: true, the autoscaler throws
> NumberFormatException while computing the observed scaling coefficient for any
> vertex with a zero true-processing-rate (idle / very low traffic). The
> exception
> aborts the entire scaling pass, so *no* parallelism overrides / resource
> requirements are applied and the job stays stuck at its deployed parallelism.
