exposing spark through a web service

[Philip Ogren]

Hi Spark Community,

I would like to expose my spark application/libraries via a web service 
in order to launch jobs, interact with users, etc.  I'm sure there are 
100's of ways to think about doing this each with a variety of 
technology stacks that could be applied.  So, I know there is no right 
answer here.  But, I am curious to know if anyone has a fairly general 
solution that they are happy with that they would recommend or if there 
is any growing consensus in this community towards a solution or family 
of solutions that align with the "Spark way" of doing things.  Any 
advice or thoughts are appreciated!

Thanks,
Philip
