Apache Spark reassigned SPARK-41006:
------------------------------------
Assignee: Apache Spark
> ConfigMap has the same name when launching two pods on the same namespace
> -------------------------------------------------------------------------
>
> Key: SPARK-41006
> URL: https://issues.apache.org/jira/browse/SPARK-41006
> Project: Spark
> Issue Type: Bug
> Components: Kubernetes
> Affects Versions: 3.1.0, 3.2.0, 3.3.0
> Reporter: Eric
> Assignee: Apache Spark
> Priority: Minor
>
> If we use the Spark Launcher to launch our spark apps in k8s:
> {code:java}
> val sparkLauncher = new InProcessLauncher()
> .setMaster(k8sMaster)
> .setDeployMode(deployMode)
> .setAppName(appName)
> .setVerbose(true)
> sparkLauncher.startApplication(new SparkAppHandle.Listener { ...{code}
> We have an issue when we launch another spark driver in the same namespace
> where other spark app was running:
> {code:java}
> kp -n audit-exporter-eee5073aac -w

> When launching the second algorithm (data-io) in the same namespace, the name
> of the configmap is the same as the one created for the previous running
> algorithm (spark-drv-d19c37843d80350c-conf-map), and since it is immutable,
> it fails.
> The solution is pretty straightforward, simply change here:
> [https://github.com/apache/spark/blob/master/resource-managers/kubernetes/core/src/main/scala/org/apache/spark/deploy/k8s/submit/KubernetesClientUtils.scala#L46]
> From val to def, so the uniqueID is always new when we call to
> configMapNameDriver:
> {code:java}
> def configMapNameDriver: String =
> configMapName(s"spark-drv-${KubernetesUtils.uniqueID()}") {code}
> We have tested and it works in our case. I could do the pull request if you
> think it is a bug
