If your cluster uses SSL, there are a few different ways to specify the keystore holding your SSL certificate. The easiest is to simply add it to your JRE's cacerts file.
You can also set a specific Java keystore and its password via Java Secure Socket Extension (JSSE) properties:
-Djavax.net.ssl.keyStore=/usr/local/myfiles/.keystore-Djavax.net.ssl.keyStorePassword=reindeerFlotilla
Once this is complete, you can simply invoke SSL as a part of your cluster builder:
.withSSL()
