Josh Elser commented on SLIDER-809:
-----------------------------------

Shoot. It looks like choosing the port for the containers is done per 
application and not per container.

When I flexed a cluster from 1 tomcat server to 2 (on my single node yarn 
"cluster"), the second container came up but tried to bind the same port which 
failed.

> I started working on an app-package for Tomcat.
> https://github.com/apache/incubator-slider/tree/feature/SLIDER-809-tomcat-app-package/app-packages/tomcat
> Some things that need to happen for a generally usable app-package:
> * -Maven module in slider for the code-
> * -Template for server.xml -- notably the port to listen on and other options-
> * Reference external WAR file
> * Fix exports so allocated port for tomcat is advertised (e.g. can view on 
> appmaster status page)
