Thomas Graves commented on MAPREDUCE-3903:
------------------------------------------

So it actually appears we are inconsistent about acls.  If you are going 
through the web ui for AM or historyserver you get one behavior where it only 
checks the job acls, but if you go through the mapred cli which goes through 
the RM, it uses yarn acls and application acls. The application acls include 
the job acls.  Note that when going through the RM it doesn't seem to look at 
mapreduce.cluster.acls.enabled at all even through it appends the job acls to 
application acls.

> in 1.0 there was a config mapreduce.cluster.administrators that allowed 
> administrators to view anyones job.  That no longer works on yarn.
> yarn has the new config yarn.admin.acl but it appears the mr app master and 
> job history server don't use that.
