Thanks! since my worker is on the same node, -Xss JVM option is for setting thread maximum stack size, my worker does show this option now. now I realized I accidently run the the app run in local mode as I didn't give the master URL when initializing the spark context, for local mode, how to pass jvm option to the app?
