Ranju commented on SPARK-34389:
-------------------------------
Attila, Thanks for your response
I also analyzed this pod Creation timeout at my end before asking you and
understood it the same way you explained.
But want to recheck with you my understanding.
Thank you so much , now I can focus on the other solution. :)
> Spark job on Kubernetes scheduled For Zero or less than minimum number of

> Key: SPARK-34389
> URL: https://issues.apache.org/jira/browse/SPARK-34389
> Project: Spark
> Issue Type: Bug
> Components: Kubernetes
> Affects Versions: 3.0.1
> Reporter: Ranju
> Priority: Major
> Attachments: DriverLogs_ExecutorLaunchedLessThanMinExecutor.txt,
> Steps to reproduce.docx
>
>
> In case Cluster does not have sufficient resource (CPU/ Memory ) for minimum
> number of executors , the executors goes in Pending State for indefinite time
> until the resource gets free.
> Suppose, Cluster Configurations are:
> total Memory=204Gi
> used Memory=200Gi
> free memory= 4Gi
> SPARK.EXECUTOR.MEMORY=10G
> SPARK.DYNAMICALLOCTION.MINEXECUTORS=4
> SPARK.DYNAMICALLOCATION.MAXEXECUTORS=8
> Rather, the job should be cancelled if requested number of minimum executors
> are not available at that point of time because of resource unavailability.
> Currently it is doing partial scheduling or no scheduling and waiting
> indefinitely. And the job got stuck.
