> Add OUTLIER_NO_FALLBACK executor roll policy
> --------------------------------------------
>
> Key: SPARK-38047
> URL: https://issues.apache.org/jira/browse/SPARK-38047
> Project: Spark
> Issue Type: Sub-task
> Components: Kubernetes
> Affects Versions: 3.3.0
> Reporter: Alex Holmes
> Assignee: Alex Holmes
> Priority: Major
> Fix For: 3.3.0
>
>
> Currently executor rolling will always kill one executor every
> {{{}spark.kubernetes.executor.rollInterval{}}}. For some of the policies this
> may not be optimal in cases where the executor metric isn't an outlier
> compared to other executors. There is a cost associated with killing
> executors (ramp-up time for new executors for example) which applications may
> not want to incur for non-outlier executors.
>
> This ticket would add the ability to only kill executors if they are
> outliners.
