--------------------------------------
Ah interesting, it sounds like the fix would be to retry config map creation on
failure.
> Unable to Mount ConfigMap in Driver Pod - ConfigMap Creation Issue
> ------------------------------------------------------------------
>
> Key: SPARK-44050
> URL: https://issues.apache.org/jira/browse/SPARK-44050
> Project: Spark
> Issue Type: Bug
> Components: Kubernetes, Spark Submit
> Affects Versions: 3.3.1
> Reporter: Harshwardhan Singh Dodiya
> Priority: Critical

> Dear Spark community,
> I am facing an issue related to mounting a ConfigMap in the driver pod of my
> Spark application. Upon investigation, I realized that the problem is caused
> by the ConfigMap not being created successfully.
> *Problem Description:*
> When attempting to mount the ConfigMap in the driver pod, I encounter
> consistent failures and my pod stays in containerCreating state. Upon further
> investigation, I discovered that the ConfigMap does not exist in the
> Kubernetes cluster, which results in the driver pod's inability to access the
> required configuration data.
> *Additional Information:*
> I would like to highlight that this issue is not a frequent occurrence. It
> has been observed randomly, affecting the mounting of the ConfigMap in the
> driver pod only approximately 5% of the time. This intermittent behavior adds
> complexity to the troubleshooting process, as it is challenging to reproduce
> consistently.
> *Error Message:*
> when describing driver pod (kubectl describe pod pod_name) get the below
> error.
> "ConfigMap '<configmap-name>' not found."
> *To Reproduce:*
> 1. Download spark 3.3.1 from [https://spark.apache.org/downloads.html]
> 2. create an image with "bin/docker-image-tool.sh"
> 3. Submit on spark-client via bash command by passing all the details and
> configurations.
> 4. Randomly in some of the driver pod we can observe this issue.
