gaborgsomogyi commented on issue #24804: [SPARK-23472][CORE] Add defaultJavaOptions for driver and executor. URL: https://github.com/apache/spark/pull/24804#issuecomment-507231411 > there's also MesosCoarseGrainedSchedulerBackend.scala which seems easy to fix to add support for this. I've double checked the mentioned file but as I see it uses `SparkConf` to get the extra java options: ``` val extraJavaOpts = conf.get(config.EXECUTOR_JAVA_OPTIONS).map { Utils.substituteAppNExecIds(_, appId, taskId) }.getOrElse("") ``` and `SparkConf` gives back the prepended value. Not yet see what can be added there.
