> Currently spark-submit supports the option --num-executors NUM only for Spark on YARN. Users running Spark on K8S can specify the requested number of executors in spark-submit with --conf spark.executor.instances=NUM
> This proposes to extend the spark-submit option --num-executors to be applicable to Spark on K8S too. It is motivated by convenience, for example when migrating jobs written for YARN to run on K8S.
