Maximilian Michels resolved FLINK-33771.
----------------------------------------
Resolution: Fixed
> Add cluster capacity awareness to Autoscaler
> --------------------------------------------
>
> Key: FLINK-33771
> URL: https://issues.apache.org/jira/browse/FLINK-33771
> Project: Flink
> Issue Type: New Feature
> Components: Autoscaler, Kubernetes Operator
> Reporter: Maximilian Michels
> Assignee: Maximilian Michels
> Priority: Major
> Labels: pull-request-available
> Fix For: kubernetes-operator-1.8.0
>
>
> To avoid starvation of pipelines when the Kubernetes cluster runs out of
> resources, new scaling attempts should be stopped.
> The Rescaling API will probably prevent most of this cases but we will also
> have to double-check there.
> For the config-based parallelism overrides, we have pretty good heuristics in
> the operator to check in Kubernetes for the approximate number of free
> cluster resources, the max cluster scaleup for the Cluster Autoscaler, and
> the required scaling costs.
