Yes, the quotes work for me.
In order to pass multiple system properties via eg
`spark.driver.extraJavaOptions`, I passed the arg in quotes on the shell to
spark-submit, but the value itself doesn't have quotes around it and ends up
broken on the commandline for the driver, unless I add escaped quotes inside
the string.
So this fails when executing the driver, but spark-submit accepts the
command:
```
bin/spark-submit [...]
spark.driver.extraJavaOptions="-Dcom.sun.jersey.server.impl.cdi.lookupExtensionInBeanManager=true
-Dorg.jboss.weld.bootstrap.concurrentDeployment=false" [...]
```
This doesn't look very intuitive to me, but it does work without wrapping
values in quotes:
```
bin/spark-submit [...]
spark.driver.extraJavaOptions="\"-Dcom.sun.jersey.server.impl.cdi.lookupExtensionInBeanManager=true
-Dorg.jboss.weld.bootstrap.concurrentDeployment=false\"" [...]
```
String interpolation doesn't support double quotes, but I've since learned
about triple-double-quoted string interpolation, that why I initially went with
`Seq.mkString`.
