How to set Java options -Xmn

Hi,
I am trying to set -Xmn  to control GC in spark.executor.extraJavaOptions
(as recommended by tuning guide), but I am getting error that
"spark.executor.extraJavaOptions is not allowed to alter memory settings".
It seems that extraJavaOptions takes just one number, not list of java
options. 

How can I set -Xmn ?
