> Spark sets up actors for akka with a set of variables which are defined in the {{AkkaUtils.scala}} class.  
> A snippet:
> {noformat}
>  98       |akka.loggers = [""akka.event.slf4j.Slf4jLogger""]
>  99       |akka.stdout-loglevel = "ERROR"
> 100       |akka.jvm-exit-on-fatal-error = off
> 101       |akka.remote.require-cookie = "$requireCookie"
> 102       |akka.remote.secure-cookie = "$secureCookie"
> {noformat}
> We should allow users to pass in custom settings, for example, so that arbitrary akka modifications can be used at runtime for security, performance, logging, and so on.
