----------------------------------
Summary: Do not wait for scaling completion in UPGRADE state with
in-place scaling
Key: FLINK-34619
URL: https://issues.apache.org/jira/browse/FLINK-34619
Project: Flink
Issue Type: Improvement
Components: Kubernetes Operator
Affects Versions: kubernetes-operator-1.7.0
Reporter: Gyula Fora
Assignee: Gyula Fora
Fix For: kubernetes-operator-1.8.0
The operator currently puts the resource into upgrading state after triggering
in-place scaling and keeps observing until the desired parallelism is reached
before moving to deployed / stable.
However this means that due to how the adaptive scheduler works this
parallelism may never be reached and this is expected.
We should simplify the logic to consider scaling "done" once the resource
requirements have been set correctly and then leave the rest to the adaptive
scheduler
