Subject Re: Tez part of YARN?
Date Mon, 11 Aug 2014 10:29:21 GMT
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..
