[jira] [Updated] (SPARK-26642) Add --num-executor option to
spark-submit for Spark on K8S
[ https://issues.apache.org/jira/browse/SPARK-26642?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.executors.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.
