> executorIdleTimeout is not working for pending pods on K8s
> ----------------------------------------------------------
>
> Key: SPARK-37049
> URL: https://issues.apache.org/jira/browse/SPARK-37049
> Project: Spark
> Issue Type: Bug
> Components: Kubernetes, Spark Core
> Affects Versions: 3.1.0
> Reporter: Weiwei Yang
> Assignee: Apache Spark
> Priority: Major
>
> SPARK-33099 added the support to respect
> "spark.dynamicAllocation.executorIdleTimeout" in ExecutorPodsAllocator.
> However, when it checks if a pending executor pod is timed out, it checks
> against the pod's "startTime". A pending pod "startTime" is empty, and this
> causes the function "isExecutorIdleTimedOut()" always return true for pending
> pods.
> This caused the issue, pending pods are deleted immediately when a stage is
> finished and several new pods got recreated again in the next stage.
