[jira] [Created] (SPARK-41006) ConfigMap has the same name when launching two pods on the same namespace
Eric created SPARK-41006:
----------------------------
Summary: 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: 3.3.0, 3.2.0, 3.1.0
Reporter: Eric
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 qa-topfive-python-spark-2-15d42ac3b9
NAME READY STATUS RESTARTS AGE
data-io-c590a7843d47e206-driver 1/1 Terminating 0 2s
qa-top-five-python-1667475391655-exec-1 1/1 Running 0 94s
qa-topfive-python-spark-2-462c5d843d46e38b-driver 1/1 Running 0 119s {code}
The error is:
{code:java}

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-34c4e3840a0466c2-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.
