-------------------------------------

Hi all, we recent push our new implementation, and you can take a look over the code at the
PR.
I'm creating a little doc to explain the solution.

BTW Some headlines.

Enable using standard principal and keytab args, also allow to use proxy user over the real
principal with --proxy-user  arg.
Diver side uses kerberos authentication 
DAGScheduler get the hadoop delegation tokens related, using kerberos authentication and create
each task with those tokens.
Executors side uses hadoop tickets authentication
