Luca Canali updated SPARK-26642:
--------------------------------
Description:
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.
