Jian He commented on YARN-4170:
-------------------------------

- priority is per application, but this is a global variable in 
ApplicationMasterService, is this wrong? 
{code}
 private Priority applicationPriority = Priority.newInstance(0);
{code}

> AM need to be notified with priority in AllocateResponse

> As discussed in MAPREDUCE-5870, Application Master need to be notified with 
> priority in Allocate heartbeat.  This will help AM to know the priority and 
> can update JobStatus when client asks.
