SLS and Tez

[Fabio]

With SLS (Yarn Scheduler Load Simulator) I can test a MR job trace 
against different schedulers, but to do so I see one has to specify 
"yarn.sls.am.type.mapreduce" that is "The AMSimulator implementation for 
MapReduce-like applications. Users can specify implementations for other 
type of applications.". As far as I understand this class is a simulator 
of the AM, so I suppose that if I want to execute a job trace as if it 
is run on top of Tez, I should implement this class in order to simulate 
a Tez AM.
Is this correct? A of today is there already some implementation of this?
Thanks in advance
