Sumit Mohanty commented on SLIDER-239:
--------------------------------------

Look at the memcached sample in "develop" branch.

https://github.com/apache/incubator-slider/tree/develop/app-packages/memcached

Specifically, look at memcached.py and see how it uses {port} which is a python 
variable defined in params.py that reads in the supplied config.

> Component instances should be able to advertise associated ports

> Some applications such as Databases(especially for databases that all nodes 
> are of the same role and can all be connected) need to know the port number 
> they are listening, so that DBAs and clients can manage the databases better.
