----------------------------------
Summary: Add Validator for Autoscler
Key: FLINK-37126
URL: https://issues.apache.org/jira/browse/FLINK-37126
Project: Flink
Issue Type: Improvement
Components: Autoscaler
Reporter: yuanfenghu
If the configured Autoscaler config is incorrect, it can be detected in advance
in flink-kubernetes-operator. However, if an independent version of Autoscaler
is used, it cannot be actively detected. We need to extract the Autoscaler
Validator and use it in the independent version of Autoscaler.
When incorrect configurations are discovered, they are reported through events
to avoid submitting them to scale and generating a large number of exceptions.
