Hello Your are correct Tez is a yarn app or client to be more precise. It is not bundled by default in hadoop 2, same as pig for example it is up to you to add it. Tez and pig are actually close in that sense that they are not services to be installed exactly but rather clients to be added and used, so very light wait to add no specific daemons etc..
