Replace default application.conf file with spark-submit

Question

My code works like:

val config = ConfigFactory.load

By default, key-value pairs are received from application.conf . Then I use -Dconfig.file = to point to another conf file.

It works great for the command below:

dse -u cassandra -p cassandra spark-submit 
    --class packagename.classname --driver-java-options 
    -Dconfig.file=/home/userconfig.conf /home/user-jar-with-dependencies.jar

But now I need to split userconfig.conf into 2 files. I tried the command below. This does not work.

dse -u cassandra -p cassandra spark-submit 
    --class packagename.classname --driver-java-options 
    -Dconfig.file=/home/userconfig.conf,env.conf 
     /home/user-jar-with-dependencies.jar
