k8s配置spark.kubernetes.driver.podTemplateFile不生效

问题： spark on k8s 需要配置Hosts ，指定 --conf spark.kubernetes.driver.podTemplateFile driver pod不生效，但是指定spark.kubernetes.executor.podTemplateFile pod生效

spark版本3.2.0 k8s版本1.16

提交命令：

bin/spark-submit
--master k8s://https://10.x.x.x:6443
--deploy-mode cluster
--name spark-pi
--class org.apache.spark.examples.streaming.HdfsWordCount
--conf spark.executor.instances=1
--conf spark.kubernetes.authenticate.driver.serviceAccountName=spark1
--conf spark.kubernetes.container.image=spark-example:v5
--conf spark.kubernetes.driver.podTemplateFile=/opt/spark/host_add.yaml
--conf spark.kubernetes.executor.podTemplateFile=/opt/spark/host_add.yaml
local:///opt/spark/examples/jars/spark-examples_2.12-3.2.0.jar hdfs:/x.x.x.xx:8020/jars/wordcount.txt

yaml文件：

apiVersion: v1 kind: Pod metadata: name: hostaliases-pod spec: restartPolicy: Never hostAliases: -ip: "10.x.xx.xx" hostnames: -"cdh104" containers: -name: cat-hosts image: spark-example:v5

分别查看driver/executor的yaml： kubectl get po spark-pi-1640312803968-driver -o yaml (未生效，没有hostAliases配置)

kubectl get po hdfswordcount-ad53e97dea43281c-exec-1 -o yaml (生效存在hostAliases配置)

查看相似问题，我试用了spark3.0/3.2两个版本driver pod都未生效
