Failed to submit spark training job as driver service account is not configurable

[ChenYi015]

I tried to submit Spark training job, refering Submit a distributed spark job - Arena Documentation.

arena submit sparkjob \
   --name=sparktest \
   --image=registry.aliyuncs.com/acs/spark-pi:ack-2.4.5-latest \
   --main-class=org.apache.spark.examples.SparkPi \
   --jar=local:///opt/spark/examples/jars/spark-examples_2.11-2.4.5.jar

And it fails with error message related to ServiceAccount:

Message: Forbidden!Configured service account doesn't have access. Service account may have been revoked. pods \"sparktest-driver\" is forbidden: error looking up service account default/spark: serviceaccount \"spark\" not found.

And there is no flags in spark submit spark used to configure ServiceAccount:

$ bin/arena submit spark --help

Usage:
  arena submit sparkjob [flags]

Aliases:
  sparkjob, spark
