chia7712 opened a new pull request #35215:
URL: https://github.com/apache/spark/pull/35215
### What changes were proposed in this pull request?
#34983 added the namespace to ConfigMap. However, the confFileMap does not
have namespace value, so it assigns the ConfigMap to "default" namespace. When
we submit spark application in non-default namespace, it causes error since it
can't find the configmap in non-default namespace
### Why are the changes needed?
The bug obstructs us from submitting spark application to non-default
namespace. see following error message:
```
kubelet MountVolume.SetUp failed for volume "spark-conf-volume-driver" :
configmap "spark-drv-2e1f4c7e54c2d4f3-conf-map" not found
```
The above error can be reproduced by following command.
```sh
export SPARK_VERSION=3.3.0-SNAPSHOT && ./bin/spark-submit \
--master k8s://https://k8s00:6443 \
--deploy-mode cluster \
--name sparkPi \
--class org.apache.spark.examples.SparkPi \
--conf spark.kubernetes.authenticate.driver.serviceAccountName=default \
--conf spark.kubernetes.namespace=yunikorn \
--conf
spark.kubernetes.container.image=ghcr.io/chia7712/spark:${SPARK_VERSION} \
local:///opt/spark/examples/jars/spark-examples_2.12-${SPARK_VERSION}.jar
```
