------------------------------------------
Summary: Autoscaler logs are full of deprecated key warnings
Key: FLINK-33770
URL: https://issues.apache.org/jira/browse/FLINK-33770
Project: Flink
Issue Type: Bug
Components: Autoscaler, Kubernetes Operator
Affects Versions: kubernetes-operator-1.7.0
Reporter: Maximilian Michels
Assignee: Maximilian Michels
Fix For: kubernetes-operator-1.8.0
We moved all autoscaler configuration from
{{kubernetes.operator.job.autoscaler.*}} to {{job.autoscaler.*}}.
With the latest release, the logs are full with logs like this:
{noformat}
level: WARN
logger: org.apache.flink.configuration.Configuration
message: Config uses deprecated configuration key
'kubernetes.operator.job.autoscaler.target.utilization' instead of proper key
'job.autoscaler.target.utilization'
{noformat}
The reason is that the configuration is loaded for every reconciliation.
This configuration is already widely adopted across hundreds of pipelines. I
propose to remove the deprecation from the config keys and make them "fallback"
keys instead which removes the deprecation warning.
