Thomas Graves commented on MAPREDUCE-3792:
------------------------------------------

So now if you are a user that doesn't have acl permissions to the job, this 
causees mapred job -status or any other command that goes to app master to hang 
since its returning host name of N/A.  The clientServiceDelegate getProxy() is 
expecting the host to be valid.  We need to fix it so it doesn't hang and 
somehow gives a useful error message to give the user some reason why these are 
failing.
                
> job -list displays only the jobs submitted by a particular user

> "mapred job -list" lists only the jobs submitted by the user who ran the 
> command. This behavior is different from 1.x.
