The properties in spark-env.sh are machine-specific. so need to specify in you worker as well. I guess you ask is the System.setproperty(). you can call it before you initialize your sparkcontext.

Hi,

I have a java option (-Xss) setting specified in SPARK_JAVA_OPTS in
spark-env.sh,  noticed after stop/restart the spark cluster, the
master/worker daemon has the setting being applied, but this setting is not
being propagated to the executor, my application continue behave the same. I
am not sure if there is a way to specify it through SparkConf? like
SparkConf.set(), and what is the correct way of setting this up for a
particular spark application.

Thank you!
