> Spark on Kubernetes: add separate pod watcher service to reduce pressure on
> K8s API server
> ------------------------------------------------------------------------------------------
>
> Key: SPARK-38668
> URL: https://issues.apache.org/jira/browse/SPARK-38668
> Project: Spark
> Issue Type: New Feature
> Components: Kubernetes
> Affects Versions: 3.2.1
> Reporter: BoYang
> Priority: Major
>
> Spark driver will listen to all pods events to manage its executor pods. This
> will cause pressure on Kubernetes API server in a large cluster, because
> there will be many drivers connect to the API server and watch for the pods.
>
> An alternative is to have a separate service to listen and watch all pod
> events. Then each Spark driver only connects to that service to get pod
> events. This will reduce the load on Kubernetes API server.
