Arthur Rand commented on SPARK-25024:
-------------------------------------

Just to chime in here. Unless a lot has changed, all of the Spark security 
features when running on Mesos are available in "vanilla Mesos", as long as you 
have the required plug-ins. The problem is that the users' suite of security 
plug-ins is impossible to predict so the spark docs only tell you how to 
_configure Spark_. Some of the questions you bring up [~tgraves], depend on the 
specific setup, for example auth when submitting jobs. However, I think it's 
safe to say that if you have a _secure Mesos_ cluster (meaning you have some 
form of plug-ins) then it'll work with Spark. 

> Update mesos documentation to be clear about security supported

> I was reading through our mesos deployment docs and security docs and its not 
> clear at all what type of security and how to set it up for mesos.  I think 
> we should clarify this and have something about exactly what is supported and 
> what is not.
